We're back! We're just one week out from last Friday's launch of Ancient Guardians, and the biggest mover in the TCGplayer Marketplace is the new Ogdoadic theme.

A lot of players are trying a lot of different things to make Ogdoadics work, and so far the highest profile attempt we've seen is probably Jesse Kotton's run at the Luxury Championship this past weekend. Kotton ran an Eldlich Rokket build with an Ogdoadic engine, packing Reptilianne Hydra and Phantasmal Lord Ultimitl Bishbaalkin. Those two cards have become a focus for hopeful Ogdoadic players, and if you've got some copies of Reptilianne Hydra buried in a binder somewhere, well, congrats, because it spiked to nearly 30 dollars.

Kotton didn't quite make the Top Cut at the LCS, but if you want to see that deck in action, you can check out a replay of his Round 3 match here. It does some crazy stuff, and with some of the best players in the game working on Ogdoadics, it's definitely the biggest deck-to-watch heading into RDI Qualifiers this weekend. If Ogdoadics can put in a successful showing in the Qualifiers, or at the Yu-Gi-Oh! Extravaganza next weekend, it could become a major force.

In the meantime players aren't waiting to find out if the deck has legs. Ogdoadics led Ancient Guardians presales last week, and once the set launched, they swept nine of the Top 10 best-selling spots in the TCGplayer Marketplace.

#10 Ursarctic Septentrion

The only card to make the Top 10 that wasn't Snake support, Ursarctic Septentrion snuck in at the Number 10 position. One of the theme's two big boss Synchros, alongside Ursarctic Grand Chariot, it's got 3000 ATK, a negation effect that blanks Xyz Monsters, and a search effect that triggers once a turn, whenever your opponent Special Summons.

One of the big shifts between release week and the prerelease period was the step up in demand for Ursarctic cards. While Ogdoadic cards still outsold Ursarctic cards by roughly 2-to-1 ratios, the Ursarctic were just barely a factor in presales, and we saw a big uptick in demand for those cards once the set actually dropped.

#9 Aron, the Ogdoadic King

As we saw in Anthony's Ogdoadic deck article, Aron's one of the four Level 8s in the strategy, and each is likely to be a one-of so you can make the maximum number of Special Summons each turn. Because these cards are likely just singletons, and aren't tough pulls, one of them didn't even make the Top 10 proper: Amunessia, the Ogdoadic Queen clocked in at Number 12.

#8 Zohah, the Ogdoadic Boundless

Zohah, the Ogdoadic Boundless and Flogos, the Ogdoadic Boundless are two of the theme's Level 4s, but compared to Nauya, the Ogdoadic Remnant and Nunu, the Ogdoadic Remnant, they're both far less proactive cards. I've seen more Ogdoadic lists skipping Zohah, the Ogdoadic Boundless and Flogos, the Ogdoadic Boundless than lists running them, so it's kind of surprising to see Zohah at Number 8.

For about ten cents a copy though, this may have just been an easy card to huck into your cart just in case it becomes relevant.

#7 Ogdoabyss, the Ogdoadic Overlord

With an impressive effect that can out some of the format's biggest threats, including Red-Eyes Dark Dragoon, there's been mounting hype for Ogdoabyss, the Ogdoadic Overlord. This card was $11 on launch day, hit a peak of $27 on Monday, after the news of Jesse Kotton's showing at the LCS pumped the value, and now it's been holding at a little over $20 through the week.

#6 Snake Rain

The Number 1 card from Ancient Guardians pre-sales, Snake Rain reprint has successfully knocked it down to about a quarter. The slide in demand may be a reflection that lots of players picked up their copies when ANGU was in presales, or it could be demonstrating that a good chunk of interest was due to the previous rarity and volatility of this card. It's weird to see Ogdoadics trend so hard, but for this card to crash to sales lower than Ogdoadic 1-ofs.

#5 Keurse, the Ogdoadic Light

Keurse, the Ogdoadic Light is one of those singleton cards, in fact, an essential combo piece for many of the deck's biggest plays, and a more versatile Level 4 than Zohah, the Ogdoadic Boundless and Flogos, the Ogdoadic Boundless. Again, Keurse, the Ogdoadic Light Market Price right now is 36 cents, so just the low price of this card probably led players to snag extra copies.

#4 Aleirtt, the Ogdoadic Dark

We can probably see the same kind of market condition kicking in with Aleirtt, the Ogdoadic Dark. This card's another essential Level 8 that's about as important as Aron, the Ogdoadic King and Amunessia, the Ogdoadic Queen, but those cards are Ultra Rares that cost way more than this, so we're probably seeing some players holding back, waititng to see if prices drop, or if they can get those more expensive cards in packs or trades.

#3 Ogdoadic Water Lily

Meanwhile the Ogdoadic theme's key spell card just can't be ignored, and at $2 a pop for a card you'll want three copies of, it's easy to see how it wound up in the Number 3 position. This card is Foolish Burial on steroids, adding an impressive Special Summon effect that's easily achievable thanks to Snake Rain.

#2 Nunu, the Ogdoadic Remnant & #1 Nauya, the Ogdoadic Remnant

Finally, the Number 2 and Number 1 best-sellers for the week were two more Ogdoadic cards that are must-runs at three in virtually any conceivable version of the deck. Whether you're looking to control the field with traps and punishing monster effects, or FTK your opponent with Phantasmal Lord Ultimitl Bishbaalkin and Number 33: Chronomaly Machu Mech, you're going to want Nauya, the Ogdoadic Remnant and Nunu, the Ogdoadic Remnant to kick everything off.

Looking beyond the Top 10, there were some interesting picks that nearly made the cut. Ursarctic Polari came in at Number 11, the essential Ursarctic support Synchro. Ursarctic Big Dipper finished the week at Number 13 to go with it. Amunessia, the Ogdoadic Queen came in at Number 12, not bad for a card now pushing the $13 mark, while TiSolfachord Beautia and Ursarctic Grand Chariot ended at Numbers 14 and 15 respectively.

It's an interesting time! I think a lot of players are a bit bored right now despite current metagames being wide open, and deck builders looking to break new ground are taking real interest in Ancient Guardians. If you own copies of Phantasmal Lord Ultimitl Bishbaalkin, Number 33: Chronomaly Machu Mech, or Reptilianne Hydra, definitely keep an eye on their values; if you want to play Ogdoatic yourself, consider snagging those cards if you can find them at a decent price. Enthusiasm for Ursarctic and Solfachord is even causing some speculation on Neptabyss, the Atlantean Prince, Deep Sea Aria, and the Secret Rare printing of Supreme King Dragon Darkwurm.

If you're trying to play the market a bit right now, I wish you the best of luck! There's a lot of opportunity in Yu-Gi-Oh, and the deluge of releases headed our way in June is only going to ramp things up.
