Etherium Abomination

The Esper artifact decks of this shard leaned on bodies that earned their keep twice, and this Horror is built to do exactly that without spending a card on a recursion outlet. Five mana for a 4/3 is an unremarkable front end; the design lives in the unearth cost, which buys the body back for and a hasty 4/3 swing before exile claims it at end of turn. That second life is the whole pitch: a creature that dies once, feeds whatever cared about its death, then returns from the yard to apply pressure or trigger an attack-step effect before leaving for good. The exile clause is the discipline. Unearth is a one-shot return, not a loop, and the replacement effect sends the card to exile if it would leave the battlefield by any means, so the second appearance never offers a second death trigger; you get the swing and the haste, not a recurring sacrifice engine. Sorcery-speed timing keeps the return honest too: you cannot ambush combat or hold it open as a surprise blocker, so committing to the second life is a main-phase decision on your own turn. The rate on the recast is where the appeal sits. A hasty 4/3 from the graveyard for three mana is a clean deal, and the five-mana hardcast is mostly the toll for getting the card into the yard in the first place.
