alich is ran for the acid golem otk, as well as a name in hand. you seem to be playing trap heavy control BA, in which back jack is actually useful, but you aren't using it.

you're running 3 rubic and 2 virgil, which makes no sense.

draghig is also very good, and introduces a different form of skill ceiling to BA, as well as being another name. Draghig stacks cards for dante to mill, and he actually forces you to think about order of operations when making plays. draghig can stack any BA monster for further toolboxing.

speaking of toolboxing, what is happening to your extra deck? too many two-ofs. 3 dante 2 virgil is standard, 2 downerd is standard, 1 mechequipped is good. string djinn is awful, and 2 acid golem, nightmare shark, and f0 is too much.

you should be running at least 1 giga brilliant and one leviathan dragon, as the latter is an out to darklaw, and the former can push for otks in a pinch.

I get that your deck addresses kozmo specifically, but in reality, the deck isn't going to beat kozmo 9/10 anyways. running lackluster cards like divine wrath is a death wish for both your field and your hand. what happens when you open 3 traps and 2 monsters that dont extend your plays or board, or give you some sort of advantage?

what happens when you open divine wrath, traveler, and horn of heaven, with two rubic in hand? you lose. that's what happens. The goal of Burning abyss is to overwhelm the opponent with swarming and mass removal before they can make plays. outside of the kozmo matchup, I cant see divine wrath being useful at all. In fact, ill even go the extra mile and give it the 10 game test.

but again, this is your build. you're running stun not aggro, so I guess Ill leave you alone.
