Wasteland Strangler
The engine hinges on a resource most decks never manufacture: cards belonging to an opponent, parked in exile, waiting to be pulled back as fuel. That single clause turns this from a body into a two-part play where your opponent supplies half the pieces, which is why it was built alongside the ingest creatures and exile-based removal that stock the pile. With an empty exile zone the enters trigger still resolves, but the "if you do" condition is never met, so nothing happens: no card to process, no -3/-3. With even one banished or ingested card ready, the 3/2 drops that card into the graveyard, shrinks a target creature by -3/-3, and stays on the board afterward as an aggressor. The design tension sits in that conditional, gating the removal entirely behind your ability to keep exile stocked. The kill is a setup play, but not a slow one: the trigger uses the stack like any other, and if the Strangler enters at instant speed (a blink effect, a flicker in response to combat), the -3/-3 lands at instant speed too, no flash required. Devoid keeps the whole thing colorless despite the black in its cost, feeding the payoffs that count colorless permanents. This is the Processor subtype at its most aggressive: most Processors merely cash exiled fodder for incremental value, but stapling a -3/-3 to the trigger converted a build-around into genuine creature removal for anyone treating exile as a stockpile rather than a graveyard substitute.
