Swamp Fane

Relic of Ravenloft
On Strahd's upkeep: Choose a creature from a player's graveyard with the least CMC and put it on the field under Strahd's control. If the creature leaves the battlefield for any reason, exile it. Creatures attack owner.
Player: May cast creature cards from their graveyard for twice their normal CMC. (Devotion color prices double as well.)
