Entomber Exarch

The choice it offers is two cards that already exist in black's toolbox, welded to a body so the slot never goes to waste. Half of it is Raise Dead, half of it is a targeted Coercion that only takes noncreature cards: recursion when you need fuel, disruption when you need to strip a wrath or a combo piece. Neither mode is exciting alone, and that is the point. The 2/2 frame is the connective tissue that makes the modal trigger worth its four mana; whichever half the moment calls for, a clock still hits the table, so the card never reads as a do-nothing if the matchup shifts under it. The design lineage is the value-creature-as-spell, the body that pays for a stapled effect that would otherwise be a card by itself. Where it earns its keep is the floor: against an empty graveyard you still take a card, against a hand of nothing but creatures you still buy back your best one. The discard mode's restriction to noncreature cards is the honest constraint, keeping it from being an all-purpose Thoughtseize on legs while still pointing it at exactly the cards black often struggles to interact with after they have been cast.
