Mortician Beetle

The trigger reads "sacrifices," not "dies," and that single word is the entire design: it fires on the act of sacrifice anywhere at the table, regardless of which player pulls the trigger or which creature goes to the yard. Build an aristocrats engine around it and the beetle becomes a beatdown clock: each token fed to a sac outlet, each Blood Artist loop, each opponent's own desperation sacrifice stacks a permanent counter on the same body. The growth compounds across the game rather than resetting, and because the trigger is symmetric, even an opponent dismantling their board for value hands you the counters. What pays for that engine is the fragility of the chassis: the base body dies to anything before the counters arrive, and the optional "may" clause does nothing to protect it (it only lets you decline a counter you would almost never refuse). The card wants a deck where sacrificing is a core loop, not incidental value, because the gap between one sacrifice a turn and three or four is the gap between a marginal pumpable creature and a finisher that outraces the drain it shares a board with. It belongs to a family of payoff bodies that scale off a sacrifice subtheme: not the engine itself, but the thing the engine feeds, converting attrition into raw power on a single attacker.
