Reaver Ambush

Exile, not destruction, is what justifies the price here: for three mana at instant speed you remove a creature so completely that no recursion, no death trigger, no indestructible clause survives it. That is premium removal, and the power-3-or-less ceiling is the toll. The clause carves out exactly the creatures black wants gone anyway: the early aggressive bodies, the value-engine utility creatures, the small enablers that hold a deck together. What it cannot touch is the thing those decks eventually want to kill, the fattened threat that closes games, which means this card is built to win the early and middle turns and hand the late ones back to something else. Black has a long history of paying a premium to upgrade destruction into exile (the color usually trades extra mana or a narrower target for the cleaner outcome), and this sits squarely in that tradition: the body restriction is doing the same balancing work that a sorcery-speed clause or a life payment does on other unconditional removal. The result is a clean, unfussy answer that asks one question at deckbuilding time: are the creatures you most need to kill small enough to fit under the ceiling?
