Grixis — Planechase Anthology Planes #33

Blue, black, and/or red creature cards in your graveyard have unearth. The unearth cost is equal to the card's mana cost. (Pay the card's mana cost: Return it to the battlefield. The creature gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)

Whenever chaos ensues, put target creature card from a graveyard onto the battlefield under your control.
