Card Details
Mana CostSet
Character Background
Rottenmouth Viper is a brutal payoff for sacrifice-heavy control and midrange decks, turning expendable permanents into a huge discount and a devastating life-pressure engine. In Bloomburrow’s grim, swampy tone, it reads like a scavenging predator that grows more poisonous the longer it is fed, and its enter-or-attack trigger makes every swing matter immediately. The best home is a deck with tokens, Treasure, or recursive fodder, since sacrificing extra permanents both accelerates the Viper and fuels later effects if opponents survive. Because each blight counter forces a painful choice—lose four life, sacrifice, or discard—it shines when you can attack safely and repeatedly, especially with evasion or ways to untap and reattack. Pair it with cheap token makers or artifacts that don’t mind being cashed in, and use removal or discard to strip away your opponent’s best sacrifice fodder before the Viper lands.
