Morbid Bloom

The conversion here runs against the grain of how most graveyard payoffs work: instead of bringing a creature back, this hauls it out of the yard for good and trades its toughness for a swarm of bodies. Toughness, not power, is the dial, which means the cards it most wants to exile are the fat, defensive walls that other reanimation spells ignore. A blocker that earned its place in the graveyard by soaking damage before it fell now pays out at its full toughness in Saprolings, which gives the spell a quiet symmetry with combat: the bodies worth the most to convert are exactly the ones that absorbed punishment rather than dealt it. The exile clause is doing double work. It pays for the token windfall, and it strips a recursion target away from an opponent's graveyard in the same breath, so the spell can read as graveyard hate that happens to leave an army behind. It is a wide, expensive, sorcery-speed effect built for decks that want a board out of nothing and have some reason to fill or raid a graveyard first, and the requirement that the exiled creature already be dead is what keeps six mana honest: you need a corpse worth harvesting before the spell does anything at all.
