Bolrac-Clan Crusher
The engine runs on cannibalizing your own counters. Every activation costs a tap and a +1/+1 counter pulled off any creature you control, which turns a mechanic normally read as pure upside (bigger bodies) into ammunition. That reframing is the whole design: in a shell built to accumulate counters, whether through proliferate, adapt, or outlast triggers, this converts stockpiled stats into a repeatable two-damage ping at instant speed. It is a Prodigal Sorcerer descendant with a nonrenewing cost, and that cost is the pressure that governs the whole card: the pinging is only as sustainable as your counter supply, so you are constantly weighing whether a creature is worth more as a threat on the board or as a magazine of shots. The 4/4 for five was never the point; the body is a fair frame with a control lever bolted on. Note that the ability can pull a counter off any creature you control, not just itself, which is the wrinkle that makes it a payoff rather than a standalone: it wants a board that manufactures counters faster than it spends them, at which point it becomes a tap-to-shoot machine that also picks off attackers and blockers. Because the counter is consumed rather than tapped for, each shot permanently shrinks a body somewhere, so the decision it forces is not "when do I fire" but "which creature do I dismantle to fire." That tension between hoarding counters and spending them is the card's reason to exist.
