Corpsemeld

As an additional cost to cast Corpsemeld, exile any
number of creatures from graveyards.

Corpsemeld enters with a +1/+1 counters in it for each
creature you exile from your graveyard and a -1/-1
counter on it for each creature you exile from an
opponent's graveyard.

Whenever a creature dies, exile it instead.

Whenever Corpsemeld attacks, it gains the abilities of a
card exiled with it until end of turn.
