Boomerang, Blade Flinger

Three toughness on a two-mana body is doing quiet, specific work: it lets this creature declare into combat turn after turn without folding to the first small blocker, since the goal was never to win fights but to keep showing up. The drain fires on the act of attacking, not on damage connecting, and that timing distinction carries the whole design. Because the trigger keys on the attack declaration, a chump block or a deterrent parked across the board does nothing to shut the engine off: the point of drain resolves regardless of what waits to block. A single swing is trivial, but this is a drip rather than a strike, compounding turn over turn, and the life gained is what funds the loop, each attack buying back a little of the risk of the next. A creature that accomplishes almost nothing on its own becomes a slow bleed that has to be answered before the math runs away. Structurally this is the small-body drain engine, the job a Suture Priest or a Marauding Blight-Priest fills, folded onto a frame cheap enough to commit early and durable enough to keep coming back. The one gate is the attack step itself: no swing, no drain. Everything hinges on sending it back in against a board that would rather keep it home.
