Red seemed to be the flavor of the week with half the Top 10 being red aggro cards. Aggro dominated the Top 8 at SCG Richmond, taking six of the Top 8 spots, so for the time being, aggro seems to be the go-to strategy. Let's take a look into what's been selling.
Standard Esper and Bant decks have been playing full sets of Teferi, Time Raveler, but there is a fair bit of diversity in the type of deck you can play Teferi in. Control, Midrange, and planeswalker decks have all been successful so far in this format. Teferi, Time Raveler's ability to shut down countermagic and slow down removal make it useful in any deck that can support it. Its +1 ability has been boosting the power level of sorceries in these decks, allowing these spells to work in ways they never could on their own. Thought Erasure is currently one of the most powerful plays with Teferi. The ability to remove freshly drawn cards from your opponent's hand during their draw step before they get a chance to cast them is usually even better than countering the spell. Teferi, Time Raveler's static ability backs this up by preventing your opponent from casting instants in response or countering your Thought Erasure.
In Modern, Mono-Red Prison has been taking advantage of Karn, the Great Creator to improve its ability to lock down its opponent's field. Due to Karn, the Great Creator's -2 ability, the sideboard in Mono-Red Prison has become more artifact-heavy. The silver bullets sitting in the sideboard can be utilized even in game one, giving you an edge with more focused answers that you wouldn't include in a maindeck. Along with those answers Karn can grab Mycosynth Lattice from the sideboard to completely lock your opponent's mana down for as long as Karn, the Great Creator is on the battlefield.
In Standard we haven't seen anything too exciting with Karn, the Great Creator since War of the Spark released but MTGGoldfish did feature a fun deck with both Standard-legal Karn planeswalkers alongside Parhelion II in their Against the Odds series. While this deck struggled to set up fast enough against aggro decks, it fared well against midrange and control. Karn, the Great Creator helps improve these matchups with its ability to tutor exactly what you need from the sideboard. Karn fans are likely buying these up to try out the deck at the next Friday Night Magic.
As we saw in recent results at SCG Richmond, Mono-Red is positioned very well right now. Runaway Steam-Kin is a great aggro card and its synergy with Experimental Frenzy to cast cards off the top of your library with Steam-Kin's mana ability makes it an auto-include in mono-red strategies.
Another star from SCG Richmond, Chandra, Fire Artisan continues its rise in popularity.
Chandra, Fire Artisan was the major addition to red decks from War of the Spark. At SCG Richmond the winning deck was playing a playset of Chandra and many other red decks were seen throughout the day with varying numbers in the maindeck and sideboard. Chandra, Fire Artisan is great against both control and the mirror which isn't something you see from many red cards. With it's increase in sales the card has been slowly creeping up in price so keep an eye out for it. Last week Chandra was sitting around $3 and it's hitting around $5 as I'm making this video. If Mono-Red continues to dominate events, expect the price to keep climbing.
An easy include in Gruul, Domri, Anarch of Bolas both mana ramps and disrupts control with its +1 ability. Domri, Anarch of Bolas's minus is repeatable removal and the static ability speeds up the clock on your opponent and even allows Llanowar Elves to get in damage when you don't need the extra mana.
Narset, Parter of Veils has been making big waves in Eternal formats. Narset, Parter of Veils slows down opposing decks that rely on card advantage, while simultaneously digging for noncreature spells. The downside of only having a minus ability is even lessened by Narset's ability to find additional copies of itself. Just from what I've seen so far, some of the decks utilizing Narset, Parter of Veils include:
Narset, Parter of Veils's static ability also combos with Day's Undoing and other wheel effects making them entirely one-sided. There's nothing that Eternal formats (including Commander) love doing more than breaking fair cards.
This feels a bit like Remand: the spell is likely coming back at some point, but your opponent has already wasted their mana and possibly entire turn only to have you get the spell. Likely for far less mana than they spent. In particular, I love the thought of countering a Nexus of Fate with it. Once Nexus gets rolling it can be hard to stop, but many times, it feels like if I just had one more turn, I'd be able to shut them down and win the game. I guess Narset's Reversal will give me the chance to find out.
With all the red decks being built, aggro players are going to need some removal. Lava Coil fills that role, being capable of removing just about everything control and midrange can throw at them. I think this is just a temporary spike in popularity from players grabbing the finishing touches to update their red decks.
Krenko, Tin Street Kingpin looks to be the only Commander card making it into the Top 10 this time. Krenko, Tin Street Kingpin really rewards the classic mono-red style of "hit 'em fast and hard." With just a Hero's Blade on the battlefield Krenko can swing for 5 the turn after it comes in making five 1/1 tokens. Goblins have been a major theme in Magic since Alpha so there are limitless options for building a commander deck with Krenko, Tin Street Kingpin. On top of that, red Commander decks are usually budget friendly which is probably why Krenko has become so popular.
For our number 1 card this week we have a one-mana planeswalker killer. Price of Betrayal can also kill a Hydroid Krasis or rip counters off any creature, artifact, or opponent. With the number of planeswalkers in Standard right now, this is probably going to start seeing some sideboard action soon in decks that can't utilize the higher-costed planeswalker removal spells.
