Vile Rebirth

Most one-mana exile effects spend their whole purpose on disruption: you point them at a reanimation target or a flashback card, deny the value, and accept that you have done nothing for your own board. This one refunds the tempo. It needs a creature card in some graveyard to resolve, so it cannot be cast into a board state where every graveyard is empty of creatures, but that is rarely a real constraint: someone usually has a blocked, burned, or pitched creature lying around, and when no opposing target presents itself, your own graveyard works fine. The 2/2 Zombie is small, yet a 2/2 for one mana at instant speed carries independent value, which is the design idea here. By stapling a body to the exile, the card keeps a useful floor even when the graveyard it targets holds nothing worth denying, because the token is the same either way. That solves the chronic problem with narrow graveyard hate: a card that does only one job sits dead when that job never comes up, while a hate spell that also builds a board still does something on every turn it resolves. The token rides along on the disruption rather than the other way around, and the only genuine whiff is the rare empty-of-creatures moment when there is no legal target to point at.
