OK, I know I'm late as f**k, but I got DOOM Eternal this month, and I absolutely love the game! So for my final deck profile of 2020, I made this go-second Burning Abyss build named after the most famous song in the game's soundtrack!
As I just said, this is a Burning Abyss deck meant to go second every single game. I'm not sure how to improve the deck, but I'm gonna give you the run down on its strategy.
The goal is to summon Dante--ideally while you also control Cherubini, Ebon Angel of the Burning Abyss. When you attack with Dante, then you summon Divine Arsenal AA-ZEUS - Sky Thunder, who is basically the BFG-9000 of Yu-Gi-Oh! AA-ZEUS by itself is broken. Sending Burning Abyss monsters to the graveyard to activate its nuke effect is OP, especially since you can send Scarm to the Graveyard to search a Tour Guide, or Dante to add Cir to the hand.
And to make matters worse, if this thing is in a zone that Cherubini points to, it can't be destroyed by card effects!
Now, an indestructible AA-ZEUS isn't this card's only strategy. If you're able to OTK, you can make Borrelsword Dragon or Accesscode Talker. As an alternative, you can link summon Mekk-Knight Crusadia Avramax with I:P Masquerena to make a near-unkillable boss monster!
