I find it works rather well against AI5 if you get a couple of early hourglasses. I even had some success against a few Gods. It is no where near optimised for competitive play, as it was originally for something else. It's more of a fun deck, like many pvp voodoo decks, chance to fail, but on the other hand can pull off some very epic wins.
