Welcome to the third and final part of my card-by-card financial set review for Kaldheim! Strap in, because we've got a lot of amazing cards to get to this week, including all three planeswalkers, the pathway lands, and one of my favorites rares in the set. 

You don't need to read the first two parts of my set review before reading this one, but if you missed them and want to see my thoughts on the rest of Kaldheim's rares and mythics, you can check them out here.

Just as a quick refresher, I'm evaluating Kaldheim's rares and mythics based on Commander demand first and competitive tabletop play second. While the tabletop Magic scene has been shut down for nearly a year now, I do expect it to be back in force at some point during Kaldheim's Standard legality. Thus, there are quite a few cards in this set that I'll be looking to pick up at some point before my LGS re-opens for in-store play. In the meantime, I expect Commander to remain the driving force behind the Magic singles market. 

On to the cards!

Mythic Rares

Kaya the Inexorable is a perfect example of WotC's current approach to planeswalker design. There's nothing too flashy about Kaya; she's not overpowered, and I highly doubt she ends up as the next Jace, the Mind Sculptor or Teferi, Time Raveler. In fact, she's really only at her best alongside a card like Skyclave Apparition, or if there's a problematic non-creature permanent on the opposite side of the battlefield. 

That said, I do think Kaya will be a popular role-player in Standard. Esper Yorion definitely wants access to Kaya, and I imagine any sort of Esper or Orzhov Control deck will consider running at least 2-3 copies of Kaya somewhere in their 75. 

Kaya the Inexorable is also going to be somewhat popular in Commander. She's not a universal staple, but she'll slot nicely into loads of different Orzhov and Esper decks. Commander demand for Kaya should remain steady for years to come, which is the sign of a solid long-term hold.

Kaya is currently selling for $7, which feels exactly right to me. If you want to buy a copy or three for yourself, you don't have to pay any sort of pre-order hype premium. Worst case, Kaya becomes a purely casual card that settles in around $5 or so. Best case, she's better in competitive play than she looks and we're talking about a $15-$20 card. If you're a Kaya believer or you simply just want a few copies in your collection, snagging them now is totally fine.

Niko Aris is a fantastic card to draw if you're stuck in a late-game board stall. Need more cards? Niko's got you. Need to force some damage through? Niko's got you. Want to re-buy your best enters-the-battlefield trigger? Niko can help with that, too.

My worry about Niko is that they're a bit clunky early in the game. You don't want to play them for three mana most of the time, and they're not all that great if you're on your back foot. Their competitive playability is going to depend a lot on how the format shakes out. If games are going long and there's a strong Azorius or Esper deck in the format, Niko is going to break games open. If not, they might end up being the rare miss for an Azorius-colored planeswalker.

Casually, Niko Aris is probably slotting into my Bant decks that revolve around re-buying creatures with strong enters-the-battlefield triggers. They have a few other solid applications, but Kaya is probably the stronger planeswalker in Commander. Their differing price tags reflect this, too. You can pick up Niko for about $6.50 right now, and as with Kaya, you're looking at a $4-$5 floor and a $15-$20 ceiling. Feel free to grab your copies now if you want them. There's very little risk.

All three planeswalkers in Kaldheim are narrow, but Tyvar Kell might be the narrowest. You do not want to run this card in a deck without a critical mass of Elves, and even then, you'd better hope you've got an Elf with a strong tap ability on the battlefield. Otherwise, Tyvar isn't doing much. 

It's kind of nice that you can tap your Elves for mana with Tyvar on the battlefield, but many of those creatures are probably going to be busy doing better things. Making a 1/1 Elf each turn isn't exactly where you want to be at, either. Tyvar's ultimate is terrific, but I would hope that we've been through enough preview seasons at this point to know that we can't rely on game-breaking ultimate abilities to carry the day in most competitive scenarios. Tyvar Kell might see a little bit of play if Elves become a competitive tribe in Standard, but I wouldn't count on it. 

In Commander, Tyvar Kell is a must-play in all Golgari-based Elf decks. There are a lot more stray tokens running around in Commander, far more Elves with great tap abilities, and that ultimate ability is far more viable, too. Demand for this card is going to be strong for a long time, too, since Elves have been one of Magic's marquee tribes since Alpha.

That said, Tyvar Kell is currently selling for $10 right now instead of the $6-$7 that Kaya and Niko are currently worth. Because of that, I'm not sure I want to buy in yet. Not only does Tyvar seem least likely to see any competitive constructed play, but his ceiling in Commander isn't quite as high as the other two. As such, I'm going to wait at least a few weeks before I buy in. I bet you'll be able to snag copies in the $5-$6 range if you're patient.  

Battle Mammoth

It's been a while since a card like Battle Mammoth has been good in competitive play. Whether you're paying five mana for your Mammoth or two and then four on consecutive turns, the end result is a fairly generic midrange creature. Battle Mammoth could be a fine sideboard card against some hypothetical black deck that focused on hand disruption and targeted removal, but the fact that this creature dies without benefit to most board wipes is going to keep it on the sidelines most of the time.

I might grab a few Battle Mammoths if they drop into the bulk mythic range, just in case some future iteration of Standard is conducive to this card's strengths, but I'm not counting on it. The fact that Battle Mammoth is a pretty underwhelming Commander card gives it a pretty low floor, and its current $6 retail price is simply too high for me.    

Resplendent Marshal

I'm not that high on Resplendent Marshal, either. A 3/3 flier for 1WW is not good enough for Standard these days, at least not without additional upside. The fact that you need a creature card in your graveyard that shares a creature type with at least one other creature on your battlefield before Resplendent Marshal does anything makes it really hard to rely on. If this card were in black, red, or green—colors with stronger competitive aggro tribal synergies—I might feel differently. In 2021 Standard, however, the number of aggressive tribal decks that can handle a 1WW mana cost are going to be pretty limited. 

I also don't think Resplendent Marshal is that great in Commander. It's an aggressive card in a format that rewards big, splashy plays. It will see some play, I'm sure, but its current retail cost is still $7—same as Kaya and Niko Aris. Both of those cards are better buys with more upside than Resplendent Marshal. 

Haunting Voyage

At its best, Haunting Voyage is a one-sided Patriarch's Bidding. I also love that you can Foretell it early in the game to avoid having your late-game bomb hit the graveyard, thanks to an ill-timed Wheel of Fortune effect. It's not a competitive card at all, but I'm going to at least consider running Haunting Voyage in all of my black-based tribal commander decks from here on out. Zombies, Dragons, Vampires…it's all on the table.

Haunting Voyage's price tag is right around $5, which seems a tad high to me. My guess is that this card will slip between the cracks a little since it's not that exciting, and you'll be able to pick it up for around $2. It's a $5-$7 card long-term, though, so I'll be hoping to buy in close to that floor and profit through patience. If you don't want to wait, however, snagging your personal copies now is okay. While I do think that Haunting Voyage will drop a little in the short-term, this card will be worth $5 again eventually. 

Orvar, the All-Form

Orvar, the All-Form is probably too slow for Standard, but it might actually see some play as a combo piece in Historic, Pioneer, or Modern. It's definitely part of some three-card combos, and the discard hate gives it some additional utility in the eternal formats as well.

Over in Commander, Orvar, the All-Form is rock solid. It's a new Commander for Mistform Ultimus Changeling decks, it plays well with a lot of that format's cheap cantrips, and Clone decks definitely want to run it. I'm not sure it's going to be a new top tier format staple, but it's definitely going to see enough play to keep demand relatively high.

Is all of that worth Orvar's current $17+ price tag? I'm not sure. It seems to be getting a little bit of a boost since it's a blue mythic with competitive combo potential, which gives me pause since the floor is still pretty low here. Commander demand will be enough to keep this card in the $5 range, but at its current nearly $20 price tag you're placing a big bet on Orvar doing something in Standard or Modern. That's not the kind of gamble I like to make, and I'll look to snag my personal Commander copy in a month or two.


The Pathway Lands

At this point, we know what we're getting with the pathway lands. They're quite good in Standard and Commander, but they're not quite powerful enough for most older formats. Their Commander playability makes them solid long-term holds, but their short-term potential is pretty much nil. 

The Zendikar Rising pathway lands are currently selling between $2 and $4, while the Kaldheim pathway lands are all kicking around between $3 and $4. A few of the Kaldheim pathways are probably going to drop a little over the coming months, but the difference should be fairly negligible if you're simply hoping to snag a set or two for personal use. I'm going to hold off just because I don't see much of a downside in waiting. If you don't feel like being patient, though, you've got my green light to pick them up now. 

Black rarely gets unconditional wrath effects these days, much less one with as much upside as Blood on the Snow. This spell is going to be a two-for-one most of the time, and the fact that it's got the ability to pick off planeswalkers if you're otherwise ahead on board makes it more versatile than it looks. Six-mana wraths do need to be good to see play in Standard, but I think Blood on the Snow makes the cut—at least as a 2-of or sideboard card here and there.

Blood on the Snow should see some commander play, though it has a lot more competition there. There were quite a lot of six-mana wraths in that format, and most of them don't require you to fill your deck with snow lands. Put all this together and you get a $1-$2 card, just slightly less than its current $2.50 price tag. Feel free to snag a copy now or two now, but there's no rush. The price will likely drop a bit over the coming weeks.  

Blessing of Frost

Blessing of Frost might be worth running if it were an instant, but at sorcery speed this looks like a limited-only card to me. There are too many better four-mana sorceries in Commander, and cards like this rarely make the cut in Standard. Future bulk rare.

Cosima, God of the Voyage is unique to the point where I'm not really sure how to evaluate it for competitive play. My gut reaction is that it's good. If you're ahead on board, you can drop The Omenkeel and enjoy one of the most efficient vehicles printed in a while. Otherwise, Cosima is a fine blocker against aggro, and an unbelievable way to draw cards against control. My only worry is that Cosima is a poor card to draw late in the game, which might prevent it from seeing as much competitive play as I'd like.

Cosima will also have its fans in Commander, though I don't see it becoming a staple. Unless you're running Cosima as your commander, there are simply too many better (and more synergistic) cards to stick into your deck as long-term card draw. It's a fun card, though, and that might help it see more play than it otherwise would.

At just under $3, you're currently paying for a decent amount of competitive constructed potential here. I'm not sure I'd do that. Its competitive success is far from a sure thing, and we're not going to see much Standard demand until the end of the year regardless. You should be able to snag your copy closer to $1 if you're patient.

I like Dragonkin Berserker. First strike is right up there with haste on my list of underrated keywords, especially on aggressive red creatures. Even just a 2/2 with first strike for 1R is solid in the right deck—especially considering the relevant creature type here—and the boast ability does a good job of making Dragonkin Berserker relevant in the mid-to-late game. I expect this card to see some competitive play.

In Commander, I can see Dragonkin Berserker making the cut in some Dragon Tribal decks. Those decks need more early drops, and the fact that this one can make Dragons late in the game makes it worthwhile. That's a pretty narrow application, though, and many of those decks will simply opt to run more dragons instead.

At any rate, Dragonkin Berserker is currently dropping toward $1, which seems like a solid price to me. Commander demand should backstop its slide somewhat, and I bet it'll see Standard play at some point over the next couple of years. I'm in for a set.  

Dream Devourer is the exact kind of card I like to bet on when a new set is previewed. There have been tens of thousands of Magic cards printed over the years, and giving them all a brand-new ability is sure to cause some shenanigans here and there! This is especially true in Commander, where Wheel of Fortune effects are quite common and foretell is quite strong. Dream Devourer is great both alongside and against wheels, making it a solid early-drop consideration in nearly every black deck in that format.

I have no idea whether or not Dream Devourer will shine in any competitive format, but it's unique and powerful enough that it wouldn't shock me. Either way, Commander demand alone makes this card a solid buy at its current retail price of $2.40. I'm in on Dream Devourer.  

Egon, God of Death is not much of a Commander card, but it's got some real potential in Standard, Pioneer, and Historic. You really need a small handful of cards in your graveyard before Egon does much of anything, but Throne of Death is a solid early play, and Egon's creature side is quite powerful in the mid-game. My guess is that this card sees competitive constructed play, perhaps in multiple decks.

Egon's current price tag is $2, and that seems fair to me. There's $5-$6 upside as well as bulk rare downside here, but I'm happy to take the over. You have to bet on raw power sometimes, and Egon seems like a good example of that.

Faceless Haven should see competitive constructed play, especially since WotC has given Snow Control a lot of interesting pieces in Kaldheim. It's not as good as Mutavault—the three-mana activation cost isn't nothing—but a 4/3 body is solid, and all of these creature-lands tend to be pretty decent. There are better options in Commander, though, and even in Standard I suspect Faceless Haven will prove to be a fairly narrow card. If you want to buy in, the current retail price of $1.50 is fine. I just don't think there's much upside beyond the $3-$4 range.

Firja's Retribution is going to see a lot of play in Orzhov and Mardu Angel Commander Tribal decks. Other than that, I don't see it. This saga is too fiddly for competitive constructed, and too narrow everywhere else. Future bulk rare.

I'm not sure why Harald Unites the Elves is twice as cheap as Firja's Retribution when this is the better card in both Standard and Commander. You need to be running Golgari Elf Tribal to use this card, of course, but it's a pretty terrific inclusion if you are. That first chapter is going to hit more often than not, and its second two chapters simply require you to have a lot of Elves in play—something that an Elf deck is going to want no matter what. 

I might write something more skeptical here as a counterpoint if Harald Unites the Elves were selling for more than $0.50, but it is not. There's no reason not to snag a few of these right now. Worst case, they're already basically at their price floor. Best case, this is a solid engine piece in Standard and Commander. 

Righteous Valkyrie

Wow, Righteous Valkyrie is good. A 2/4 flier for 3 is pretty solid as it is, and this card is both enabler and payoff in a tribal lifegain deck. Angel and Cleric are both relevant creature types, and gaining life equal to their toughness with this in play makes Righteous Valkyrie's second ability attainable. Righteous Valkyrie is going to be a solid card in Standard and Commander, making it a decent buy at its current retail price of $2.50. There's not a ton of short-term upside here, but it's going to hold its demand for years to come.
Runeforge Champion

Runeforge Champion is a subset tutor like Stoneforge Mystic, and cards like this are always going to give me pause. That said, I'm not seeing it yet. The current batch of runes are merely okay—Runeforge Champion might see a small amount of play in Standard, but it's not quite good enough for Commander. That's where cards like this should really shine.

Runeforge Champion will spike if WotC ever prints more runes, though. That makes Runeforge Champion a really intriguing long-term penny stock spec. Its current price tag is $0.50 and trending downward, so you should be able to snap them up for next to nothing at some point. I'll be picking up a small box of these if I can snag them for $0.10-$0.20 each. Worst case, I'll bulk them out in the future. Best case, I'll sell them to some speculator for a few bucks each next time WotC drops some runes.

Jorn, God of Winter is being overrated right now. People are comparing his creature side to Wilderness Reclamation, as if he wasn't a 3/3 for 3 without haste or evasion that has to attack before anything gets untapped. 8 times out of 10, Jorn comes down on a board where he won't be able to do much of anything at all.

Kaldring, the Rimestaff is better. Snow control decks are definitely going to run at least a copy or two of Kaldring, especially since they'll probably be based in Dimir. They might even run a couple of green snow duals to ensure that they have access to the creature side in a pinch, too.

It's possible that Jorn will see a little play in Commander, but I don't think it'll be a staple. You have to be playing at least Sultai colors to stick this in your 99, and it's a fairly weak (albeit somewhat fun) Commander to build around. Casual demand isn't high enough to prop this card up to its current retail price of almost $3, though, and since I'm somewhat bearish on its constructed hype, I won't be picking Jorn up right now. I bet it'll settle in closer to $1 than $3.

I have no idea where Magda, Brazen Outlaw will end up seeing play, but I strongly suspect that it will. There aren't enough Dwarves to make it work in Standard right now, but this is a pushed Standard card if a future set gives us at least 2-3 solid Dwarf options. This is an even stronger card in Commander, where it has already inspired a bunch of cool new Dwarf, Dragon, and Treasure-related brews. 

Magda's current retail price is hovering right around $1, which seems low for a card this good. It's a future Commander staple at worst and a constructed sleeper at best. Its applications might be somewhat narrow across both spheres, but at just $1 this is a solid buy regardless. I'm in for a set. 

Mystic Reflection is one of my favorite cards in Kaldheim, if not my straight-up favorite. The versatility is what matters here—some of the time, Mystic Reflection will work as kind of a counterspell for your opponent's best creature or planeswalker. Other times, it'll turn one of your weakest plays into one of your strongest. It works especially well with any card that makes multiple tokens in a turn, which is why I expect it'll be incredibly popular in Commander. Every token deck out there that runs blue is going to want this, and many other decks are as well.

Mystic Reflection is currently selling for a touch under $4. That feels a tad low to me. Long-term, this is a $5-$8 card. You can hold off for a bit and hope to snag a few copies for $2-$3, but it's equally likely that this card will only go up in price as more people play with Mystic Reflection and realize how good it is. I'm going to snag my set ASAP.

Tergrid, God of Fright is a really good card. This is immediately one of the strongest mono-black Commanders out there, and an immediate figurehead for everybody's edict and discard decks. I've already seen a lot of Commander regulars building around Tergrid, and cards like Pox have spiked due to increased demand. This card is going to be all over the place in Commander for years to come.

Tergrid might see some play in Standard, too. Tergrid's Lantern is the exact kind of grindy control card that I want to be good, and it might get there if the format is slow enough. This is a Commander card first and foremost, though, and that's why I expect Tergrid to hold its value over the long haul. Add this one to the list of cards to pick up when Kaldheim bottoms out. 

The Bears of Littjara might be okay. If your opponent doesn't kill your 2/2, it'll turn into a 4/4 that kills something most of the time. That's not a bad rate for three mana, at least in Standard. This isn't a Commander card, though, and to be honest, it's probably a limited-only card. I like it more than some of these sagas, though, and wouldn't be totally shocked if it saw play. I just expect it'll probably end up being a bulk rare.     

Berserker Tribal decks might run The Bloodsky Massacre, but I'm still not fully convinced of that archetype's success. Even still, we'd be talking about a $2-$3 card at best. Otherwise, this is a bulk rare with little to no Commander demand. I'm not terribly interested. 

The Raven's Warning will probably see a little bit of competitive play, particularly in decks like Yorion Control. This might be enough to keep the price at or near $1, but I doubt it. There are a lot of amazing cards at the three-mana mark, The Raven's Warning is both narrow and a touch underpowered.

As for Commander, The Raven's Warning doesn't do much unless the Commander Rules Committee changes the current "wishboard" rules. If that ever happens—and I hope it does—The Raven's Warning could see a small price spike, alongside cards like Glittering Wish and Cunning Wish. For now, though, I don't want to spend more than $1 on a Standard fringe player that won't do much in Magic's most popular format.

Tundra Fumarole is a really nice card. It's only playable if your deck is full of snow mana and you've got more than a few spells that you can use three colorless snow mana to help cast, but those don't seem like terribly high bars to me. I can imagine several snow control or big red decks taking advantage of Tundra Fumarole's mana generation ability. Remember: throughout the history of Magic, "free" spells have nearly always been a lot better than they've looked.

Financially, there's literally no reason not to buy a few sets of Tundra Fumarole right now. They're currently selling for just $0.45 each, which is bulk rare prices. Best case, this is a $5+ format staple. Worst case, you're out a couple bucks.

Tyrite Sanctum is a future Commander staple. In that format, every deck has a legendary creature that could use indestructibility, and the +1/+1 counter isn't half bad, either. There are only so many colorless lands you can hope to stuff into your Commander deck before it becomes difficult to cast spells, but Tyrite Sanctum looks like one of the better ones to me.

Right now, Tyrite Sanctum is $2.50 and trending down. This is one of those cards I'll be looking to pick up in 2-3 weeks, ideally in the $1 range. It's not flashy enough to spike right away, and it doesn't combo with a lot right now, but the next time WotC releases a god-heavy set? Tyrite Sanctum will probably jump into the $5-$8 range. Get your copies before that happens. 

Waking the Trolls is too slow and expensive for competitive constructed play. I can't imagine anyone wanting to run a six-mana land destruction spell in their deck, except maybe as a finisher in Modern Ponza or something. Even that wouldn't spike demand enough to keep the price out of the bulk rare range. This is slightly more playable in Commander, I suppose, but demand will be far from robust. Future bulk rare. 

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Birgi, God of Storytelling is a fantastic Commander card that should be good enough to see competitive constructed play as well. The fact that her creature side and artifact side are both conducive to wild infinite combos make me happy, because the God of Storytelling is going to create a lot of wild game-states that will inspire awesome stories of their own. 

Financially, Birgi looks like she's settling in somewhere between $6 and $7. You're definitely paying a premium for the combo potential at that rate, so I might hold off for a bit. Don't mistake that as me disliking Birgi, tough. It's really hard for non-mythic rares in current sets to maintain price tags in the $7-$10 range these days, so taking the under is just a safe bet. Hopefully I'll be able to snag my personal copies closer to $3.

Crippling Fear

Crippling Fear is a solid card. It's fantastic both in and against tribal decks, aggro decks, and even in midrange mirror matches. -3/-3 makes combat really difficult for your opponent even if you fail to wipe their board, and this can be close to a one-sided wrath in, say, a Golgari Elf deck. It's less good in Commander, since creatures tend to be a lot bigger there, though it might still be worth running if you run into a lot of token-based brews.

Crippling Fear is currently a $2 card and trending up, which seems about right. Best case, this is a $4-$5 format staple with some casual interest. That doesn't make me interested in speculating on Crippling Fear, but grabbing a few now is fine if you want to play with them.

Doomskar is the new best mass removal spell in Standard. Move over, Shatter the Sky! Five mana is a bit much for an unconditional wrath, admittedly, but the Foretell ability really pushes this one over the edge. You can either cast it a turn earlier than most wraths, or use that extra two mana at the end of some turn to buy yourself some extra protection. I can't imagine playing a white-based control deck in Standard and not running Doomskar.

Is Doomskar worth its current $6 price tag, though? I'm not sure. Shatter the Sky never broke $2, and I don't think Doomskar is going to see much play outside of Standard. It's fine in Commander, but so are plenty of other wrath effects. At $6, you're probably placing a bet on this card to break out in Modern, which I don't see. Hold off a few months, buy in around $3, and watch the price start to climb once the pandemic comes to an end and the Standard market gets frisky again.

Glorious Protector

I want to compare Glorious Protector to Restoration Angel since they look sort of similar, but they don't play out in similar ways at all. Restoration Angel flickers a single creature immediately, while Glorious Protector's goal is to protect your entire board from mass removal.

Is that good enough? I don't know. Even in control decks, I'd rather play proactive creatures than reactive ones, so I'm probably only going to consider running Glorious Protector in an Angel-based Commander deck or as a sideboard card in Standard against control decks running cards like Doomskar. That might command a $1-$2 price tag, but this card is currently selling for $3.50. I don't see it, and I'm out unless the price comes down a bit.   

Icebreaker Kraken

I'm going to run Icebreaker Kraken in my Sea Monster Tribal Commander deck, but I don't see a lot of promise for this card beyond that. The fact that it doesn't tap your opponents' things when it comes into play really hurts, as does its lack of evasion. Future bulk rare.

King Narfi's Betrayal

It's possible that a Dimir-based control deck wants King Narfi's Betrayal as late-game card draw, since it does a (very poor) imitation of Dig Through Time for just three mana. The randomness and ability to only pull creatures and planeswalkers hurts, though. My guess is that King Narfi's Betrayal ends up as a future bulk rare. 

This Week's Trends

We're in yet another cycle of Reserved List spikes, so let's take a quick look at how some of the heaviest hitters and recent gainers are doing. Here's Wheel of Fortune

This is a pretty big change from last week, when there weren't actually any sales over $300. We now have a few sales in the $500-$600 range, with the lowest LP copy still selling for a whopping $280. At this point, we can definitely say that this spike is real and being supported by the market. That doesn't mean Wheel of Fortune won't trend downward again at some point—I suspect it will—but this spike was no flash in the pan.

Speaking of Revised buyouts, take a look at Fork:

Yet again, we don't have any buyout spike here, and no sign of speculators manipulating the market. Even still, Fork has gone from a $40 card to a $120 card in a matter of weeks. If things keep going this way, expect all the best cards in Revised to see similar spikes over the coming months.

Looking at Memory Jar, however, we see something very different:

Yeah, that's some spike activity all right. Interestingly enough, the first two big spikes look to be market manipulation—speculators snagging copies to flip—but that last large spike was mostly single buyers, and is pretty clearly the result of a community scared of FOMO. 

What tends to happen with these Reserved List buyout right now is that someone will write about (or do a podcast episode about) a card like Memory Jar, sometimes to facilitate their own spec, and sometimes because they're simply looking for undervalued or underrated cards. Since there have been so many spikes lately, a whole bunch of Commander players and MTG finance folks will rush in to buy a copy or two, "just in case." As a result, the card spikes for real. This is happening over and over recently, especially since there's such low supply on these cards right now. Since there haven't been any events for almost a year, there are fewer vendors buying cards, which means fewer cards on the market. That leads to a lower overall supply, especially of older cards like this, which can result in crazy buyout spikes when the market dries up.

Of course, sometimes it's just regular old market manipulation. Check out this Braingeyser buyout, where two different people cleaned out the available supply and forced the spike:

Ditto for this Ice Cauldron buyout. Exact same behavior:

And same for Bubble Matrix:

Or Gustha's Scepter:

As always, don't worry too much about Reserved List cards that nobody actually needs or plays with. They might keep their high prices if the grading/collectable craze comes to Magic at some point this year, but for now? You can safely ignore these buyouts. The cards that people actually want, like Memory Jar and Wheel of Fortune, are likely to keep most of their gains. These other cards are not.
