As an additional cost to cast this spell, you may sacrifice any number of nonland permanents. This spell costs 1 less to cast for each permanent sacrificed this way. Whenever Rottenmouth Viper enters or attacks, put a blight counter on it. Then for each blight counter on it, each opponent loses 4 life unless that player sacrifices a nonland permanent or discards a card.
