Mercy Killing

Removal that hands the table back a board, scaled to exactly what it killed. The split mana tells you who wants it: a white deck that needs a clean answer and a green deck content to swap one big body for a heap of small ones. The wrinkle is the targeting math, because the creature's controller is the one who sacrifices and the one who pockets the Elf Warriors. Aim it at an opponent and they surrender a fatty for X 1/1s that rarely add up to what they lost; aim it at your own creature and you split a single body across the board for combat tricks, sacrifice fodder, or anchoring an anthem. The compensation reframes it: nobody walks away empty-handed, so the spell plays as a trade where whoever chose the target usually keeps the better end. What it solves matters as much as what it doesn't. Sacrifice never checks indestructibility, so this kills creatures ordinary destruction cannot touch. But it targets, so a hexproof creature you don't control is off-limits, and the sacrificed creature still moves from the battlefield to the graveyard, firing any death trigger in full. Everything lives in that exchange: kill anything destruction-proof, and pay your opponent power-worth of bodies for the favor.
