Kozmourning

Continuous Trap Card

Monsters destroyed by battle with "Kozmo" monsters you control are shuffled into the Deck instead of going to the Graveyard. You can banish this card from your Graveyard; the first time you would take battle damage from a battle involving a "Kozmo" monster you control this turn, gain that much LP, instead.
