in its mana cost.Toxic Deluge gives black decks a scalable creature sweeper for three mana. You choose how much life to pay, and every creature gets that much negative power and toughness for the turn. It suits control, graveyard, and sacrifice decks that need a dependable way to recover from a crowded board.
Reducing toughness to zero can remove indestructible creatures, because the effect does not depend on destroying them. It also does not target, making hexproof ineffective against the reduction. Those qualities help Deluge answer creatures that can survive ordinary damage-based or targeted removal. Your own creatures receive the same reduction, so calculate the amount around the entire battlefield.
Blood Artist and Zulaport Cutthroat can turn the resulting deaths into life swings. If they die alongside other creatures, their relevant death triggers still happen. An aristocrats deck can therefore clear the board while gaining value from creatures it was prepared to lose. Reanimate offers a follow-up by returning a useful creature from a graveyard after the sweep, although both cards put pressure on your life total.
The life payment is an additional casting cost: you pay it before opponents decide whether to counter the spell, and a countered Deluge does not refund it. Pay enough to handle the important threats rather than automatically choosing the largest possible number. Creatures entering after Deluge resolves are not affected by that resolved spell, so an opponent may rebuild or add a flash threat afterward. This is efficient cleanup, not a lasting restriction on creatures.
