Deadeye Harpooner

Conditional removal stapled to a body, with the condition built to make you act before you react. Revolt wants a permanent to have left the battlefield under your control this turn, and the cleanest guarantees are a sacrifice outlet, a fetchland crack, or a token that already traded in combat. The double restriction is what keeps the rate from being straight-up removal with a 2/2 attached: you have to have already lost a permanent, and the target has to be tapped. The tapped clause is the quieter half of the design. On your own turn, the trigger will not reach an untapped blocker or an attacker mid-swing; it wants a creature that committed to the red zone last turn and is still tapped when yours comes around, or one your opponent left tapped from their own attack. The wrinkle is that the trigger keys off entering the battlefield, not off your main phase: flicker it in at instant speed, or blink it during combat, and it can pick off a tapped attacker before damage. Revolt is an intervening-if, so if no permanent has left when the harpooner enters, the ability never triggers at all: no target, no whiff, just a 2/2. That is the honest tax for putting removal on a stick. The enabler requirement, not the body, defines where the card belongs: it wants a deck that produces a permanent-leaving event as a matter of course, so the harpoon comes free rather than hoping to draw the trigger on time.
