Alpha Deathclaw

The card asks the same question twice and answers it the same way both times: destroy target permanent on entry, then destroy target permanent again when it becomes monstrous. That doubling is the design's whole pivot. A six-drop that removes a permanent as it lands is already crowded out by value bombs of every stripe; what sets this one apart is that the removal is renewable, stapled to a body that grows into the second copy. The monstrosity price is steep on purpose, well north of the cast cost, because paying it buys a second targeted kill on top of the four counters that push a 6/6 into 10/10 territory. Trample and menace do the connective work: a body most boards cannot double-block and cannot chump cleanly converts removal-on-a-stick into a clock. The one honest limitation is that the second trigger fires exactly once, since monstrosity is a one-time switch; there is no loop, no repeatable board control, just two guaranteed answers bracketing a threat that keeps swelling. It belongs to the Golgari tradition of creatures that refuse to trade down: a body that eats a permanent, survives the exchange, and eats another when you have mana to spare.
