Tendrils of Corruption - Duel Decks: Nissa vs. Ob Nixilis (Common) [DDR-63]

Tendrils of Corruption is a three-mana instant from the Duel Decks: Nissa vs. Ob Nixilis that deals damage to a target creature based on the number of Swamps you control, while also allowing you to gain life equal to that amount. This makes it an effective removal option in black decks, especially those focusing on a heavy Swamp count, as it can swing the game in your favour by both eliminating threats and providing life gain. However, it requires a commitment to a Swamp-heavy mana base to maximise its potential. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
