Postmortem Professor

That reanimation cost is the whole strategic argument, and it draws on a fuel source most aggressive black creatures never touch. Bringing this 2/2 back for plus an exiled instant or sorcery from your graveyard means the Zombie Warlock only earns its keep alongside a stream of cheap spells: cantrips, removal, burn, tempo plays that end up in the bin anyway. That single line binds a creature meant to swing every turn to a spell-heavy shell, precisely the kind of deck that usually runs few creatures and would rather not lean on a recursive attacker at all. The attack trigger keeps the pressure honest even when the loop sputters, draining and gaining a life on each swing so a pair of these grind out a game on their own. And the can't-block clause is the cost that pays for the rest: this body only ever wants to point forward, never hold back, so the recursion never curdles into a defensive stall. Buying back a two-power attacker for two mana and a spent card looks unglamorous, but the payoff belongs to a shell that reads its graveyard as a battery rather than a memorial, cashing used cardboard into a repeated, incremental clock. It sits in the black lineage of recursive threats that demand a second resource beyond mana; its particular ask (spells, specifically) is the thing that tells you exactly what kind of deck has room for it.
