Magnitka, Risen From Hell

Flying, Haste
Whenever you cast a spell that targets a player
or a creature an opponent controls, put a +1/+1
counter on Magnitka.
When Magnitka leaves the battlefield, return
three target creature cards from your graveyard
to your hand. If all those creatures are black,
you gain 6 life. If all those creature are red,
target opponent deals 6 damage.
