Vengeful Rebel
Revolt was an experiment in stapling a reward to attrition you were already paying for, and this body is the cleanest illustration of what the mechanic asked of a deck. The -3/-3 only fires if a permanent left the battlefield under your control that same turn, which sounds like a fee until you notice how many things already feed it: a fetched land cracking, a clue or treasure spent, a token expiring, a sacrifice outlet eating something it wanted to eat anyway. The trigger turns ordinary churn into a removal spell riding a 3/2, and the design lives or dies on whether your deck is built to shed a permanent on purpose, before this hits the stack. Without that engine, you get a plain beater whose ability quietly does nothing; with it, you get a creature that kills most early threats and walks past most chump blockers in the same play. That conditionality is what revolt as an ability word was for: it priced the bonus at zero mana and instead charged a deckbuilding tax, asking you to want disposable permanents for reasons beyond this one trigger. Sequencing is load-bearing, since the loss has to register inside the same turn the creature enters: crack your fetch first, then cast this. Read alone, it is a slightly worse removal spell on legs; read inside a sacrifice or fetch-heavy shell, it is removal that also blocks, attacks, and dies into the next one.
