Reassemble the Party

This spell costs {1} less to cast for each creature
in your party.
At the beginning of the next end step, exile all
Cleric, Rogue, Warrior, Wizard, and Ally
creature cards from your graveyard that were put
there from the battlefield this turn. For each
creature card exiled this way, create a tapped
token that's a copy of that creature, except it's
2/2 and it's a Zombie in addition to its other
types.
