Hell's Oven

Eminence:
If "Asmoranomardicadaistinaculdacar" is your commander you may have creatures of any
color in your deck. If the creatures in your deck
are not your commanders color identity they
cannot enter the battlefield.
At your upkeep if every creature type that is in
"The Underworld Cook" book has been sacrificed
or discarded you win the game.
"To cook the things I have, you need a helluva oven."
