Ashnod's Harvester

A colorless 3/1 for two mana wired to a black comeback clause and a graveyard-hate rider: the design serves two masters at once. The attack trigger forces you to exile a card from a graveyard, which reframes the body from a plain beater into a repeatable disruption piece against reanimator and delve strategies; each swing chips a resource off the top of an opponent's yard while it does its damage. The trigger is mandatory and strictly targeted, but "target card from a graveyard" is broad enough that you rarely have to eat your own material: a spent removal spell, a fetched-away land, any leftover in the opponent's yard satisfies it, and only a genuinely empty enemy graveyard forces the gun to point back at you. That flexibility pairs with the card's own recursion. Bringing it back for a black and one gives you a hasty attacker whose swing feeds the same exile engine, and the end-step exile clause means the body never lingers to be answered on the crackback. The 3/1 frame is the honest price: it dies to almost anything and trades down in combat, so its job is to connect once, land its exile, and either die into an unearth or come back for a second lap. It is a construct built to be killed, then killed again, and the graveyard attrition it hands out along the way is the whole reason to keep sending it into the red zone.
