Arcane Justice

Destroy target creature that dealt damage this
turn. If there are two or more instant or sorcery
cards in your graveyard, exile it instead.
Magecraft - Whenever you cast or copy an instant
or sorcery spell, if Arcane Justice is in your
graveyard and you've cast 3 or more instant or
sorcery spells this turn, return it from your
graveyard to your hand.
As long as there is evil, there will be justice.
