Rot-Curse Rakshasa

A 5/5 with trample for two mana is priced like a mistake, and Decayed is the invoice that comes due: it cannot block, and it dies at end of combat the first time it swings. You get one enormous hit, then it is gone. What separates this from an ordinary Decayed token is the Renew clause, which turns the corpse into a weapon aimed at the opponent's board. Once it is in the graveyard, exiling it hangs a decayed counter on X target creatures, saddling their own blockers and attackers with the same one-and-done curse the Rakshasa lived under. That is a genuinely nasty second act: a scalable removal-adjacent effect that punishes go-wide boards not by killing creatures outright but by making them expendable, unable to hold the ground they were meant to defend. The design rhymes with unearth and flashback in that the card wants to be traded early and cashed in late, but the payoff is inflicted rather than gained. The sorcery-speed restriction on Renew keeps it from ambushing combat, so both halves of the card operate on your own turn, on your own terms: crash in for five, then, later, hand the decay back across the table. It is a demon that fights the same war twice, once as a body and once as a debt collector.
