INOV Subterrors Part 2: Subterror Metalfoes

A couple weeks ago I individually broke down what each of the four new Subterror cards out of Invasion: Vengeance do, but I've been holding off on a deck list until I had one that I was fully confident in. It's always difficult piloting rogue strategies like Subterrors because there aren't as many people testing them. If you're playing ABC's there are thousands of people trying out different tech choices and build concepts every single weekend, all of them generating information that can inform your build. But dedicated Subterror players are few and far between.

As of right now there's really no “standard” list for Subterrors with the new cards. Today we'll be looking at my variant of Subterror Metalfoes, and even a quick Youtube search shows that there's a ton of contention on which Subterrors should be played, how many Metalfoes are needed, and if you should play traps at all.

While some people are using other themes in their Subterror decks, Metalfoes are pretty widely accepted as the way to go amongst more competitive duelists. The key interaction is between any Metalfoes monster and Subterror Nemesis Archer. When you use a Metalfoes Pendulum Effect to pop Archer, you get to Special Summon any Subterror from your deck in face-up or face-down defense.

Card Text

At the start of the Damage Step, if this card attacks an opponent's face-down Defense Position monster, and you control another "Subterror" monster: You can shuffle that opponent's monster into the Deck. If this card on the field is destroyed by battle or card effect and sent to the Graveyard: You can Special Summon 1 "Subterror" monster from your Deck in face-up or face-down Defense Position. You can only use each effect of "Subterror Nemesis Archer" once per turn.

That's wildly important, because whenever a monster you control is flipped face-down you can Special Summon a Subterror Behemoth from your hand. The lowest leveled Subterror Behemoth monster is Level 5, so there hasn't been a good way to bring them out from your hand until now. Every Subterror Behemoth has the same effect that lets you flip it face-down once per turn, so a single Metalfoes with Nemesis Archer can get all the Subterror Behemoths from your hand onto the field in one go.

Besides that, tributing the Metalfoes monsters for Subterror Nemesis Warrior is awesome, because you can immediately Pendulum Summon them back to the field. Warrior lets you dump a Subterror from your deck to the graveyard, and then you tribute monsters on the field with equal levels or more to Special Summon the sent monster. That effect has always been great, but now it's even better for setting up your Pendulum Summons. Since you're often starting your turn with one or two Metalfoes on the field thanks to Metalfoes Counter, Warrior can often push your plays to the next level.

I talked about this in Part 1, but it's unclear which Subterror Behemoths are worth playing. I'm still a fan of Subterror Behemoth Stalagmo and Subterror Behemoth Umastryx, even if they're both from the first wave of Subterrors. Stalagmo has a gigantic 2800 ATK and digs through your deck by discarding Subterrors, while Umastryx has a powerful, permanent banish effect for your opponent's monsters. Subterror Behemoth Stygokraken is good because it's Level 5, and Subterror Behemoth Ultramafus is good because it's a Book of Eclipse without the drawbacks, but neither of them are great.

The biggest challenge with this build is actually deck space. You want to play enough Metalfoes to have a consistent enabling engine, you want to play enough Subterrors to see them in your opening hand, and you want to keep the deck count as low as possible. But as I've mentioned before, there's a ton of synergy between Subterrors and other themes. Speedroid Terrortop can make an instant M-X-Saber Invoker to bring out Subterror Nemesis Warrior from the deck; Prediction Princess Tarotrei gives you power and disruption, triggering your effects on your opponent's turn; and Brilliant Fusion sets up crazy combos that have been integral to Subterrors thus far.

Obviously, a deck with all those cards couldn't function reliably. Mismatched hands have always been an issue for rogue decks, so I'm going to want this deck as consistent as possible. Here's what I've come up with.

Okay, so right off the bat you might have noticed the biggest swerve that this deck takes from previous incarnations. For the most part, it's stripped down to just Subterrors and Metalfoes. The only off-theme monsters are Maxx “C” and Blackwing - Gofu the Vague Shadow. I'd hardly consider Maxx “C” an off-theme monster anyway because it always sits in your hand, and Gofu's practically a Metalfoes monster at this point.

I felt like I had to play Gofu for its versatility. Summoning two Tokens is fantastic with Metalfoes because you can pop them to set spells and traps for free, but it's even cooler here for making Ultimaya Tzolkin. Even if you just have one Metalfoes and Gofu, as long as you can get to Archer you can destroy it with the Metalfoes to bring out Subterror Behemoth Stygokraken from your deck, and then send it and Gofu to the graveyard to make Tzolkin. In standard Metalfoes decks you have to Fusion Summon Metalfoes Adamante, which usually requires a very specific hand of four Metalfoes and Gofu.

That's A Lot Of Triples
You might have also noticed that this deck's packed with three-ofs, and that it's 50 cards. Simply put, you want as many Metalfoes and Subterrors as you can get through all stages of the game. If you cut back on them you're killing your longevity. Pot of Desires factors in as well, and with 50 cards you're not likely going to banish everything you'd need. In terms of Subterror monsters there's actually just nothing to cut, and with the Metalfoes the only other option is getting rid of everything except Volflame and Goldriver. What then happens you'll never get to fully abuse your Pendulum Summons, and Pot of Desires becomes super dangerous.

Also a factor: I never want to see multiples of anything. An ideal hand would be three different Metalfoes monsters and two Subterrors, one of which is Archer. You've got a ton of opportunities to get that opening hand, and that leads to some great combos that I showcased on my Youtube channel. Some are simpler, only taking any Metalfoes, Archer, and The Hidden City. Others are more complicated, but yield insane results.

One tech I fell in love with is Book of Eclipse. Defensively, you can use this to stun your opponent's plays and reset all your monsters face-down. Aggressively, you can force ABC-Dragon Buster's tag out and lay the groundwork for Subterror Nemesis Archer to spin things back into the deck. Whenever Archer attacks a face-down defense position monster it shuffles into your opponent's deck, which is a fantastic way to get rid of problematic cards. Even if you give your opponent a couple draws during the End Phase you can usually make a kill on the next turn. The Subterror Behemoths are enormous and can seal the duel faster than a regular Metalfoes deck normally could.

I've also really liked Dimensional Barrier in this deck. I heavily considered just running Grisaille Prison because of the Metalfoes Fusion Monsters, but it conflicted with Ultimaya Tzolkin too much. Solemn Strike is also a viable choice, but Dimensional Barrier has so much stopping power that it's hard to pass up.

At the end of the day, I'm still not sure if Subterrors are truly competitive. This is definitely a fun deck that can crank out successful wins against the best strategies, but it's missing defensive options and stopping power. One of the issues that will hopefully be addressed in the next wave of support is the lack of flipping abilities during your opponent's turn. Subterror Burrowing was so close to being amazing, but it unfortunately flips your monsters face-down, not face-up. Prediction Princess Tarotrei is the only good way to change your battle positions, but its engine takes up a ton of space and it's inconsistent at best.

Overall, I'll still be standing by Subterrors as my go-to casual deck, and I was happy to see a card like Subterror Nemesis Archer throw into the mix!
