Fresh Meat

Most reactive green spells answer a single threat; this one waits for catastrophe and converts it into an army. The engine is the phrase "this turn," which means the deaths have to precede the resolution: the creatures must already be in your graveyard when this resolves, so the right line is to let a sweeper finish, then cast it once the bodies have actually died. Cast it before the destruction and there is nothing to count. Time it correctly, after a Wrath of God or a Damnation has cleared the board, and the graveyard full of your own dead creatures becomes a fresh wall of 3/3 Beasts at instant speed, untouched by the resolution that killed everything else. The mass-removal case gets the headlines, but any creature put into your graveyard from the battlefield qualifies regardless of cause: a sacrifice outlet emptied in response, a fight spell that trades, a turn of chump blocks all feed it. The cost of that flexibility is total dependence on the board state. With nothing dying, four mana buys you no token and no body to show for it, which is the trap hiding inside what its cost might suggest is a green fatty. That is the real identity here: a payoff card disguised as a creature-maker, an instant-speed punish for symmetrical destruction that rewards reading the table and holding four mana for the exact moment the board comes apart.
