Zombies you control get +1/+1.

: Target creature card in your graveyard gains embalm until end of turn. The embalm cost is equal to its mana cost.
(Exile that card and pay its embalm cost: Create a token that's a copy of it, except it's a white Zombie in addition to its other types and has no mana cost. Embalm only as a sorcery.)
