# Swell of Courage Swell of Courage is a straightforward combat trick from Duel Decks: Elspeth vs. Tezzeret, designed to fit the white-aligned Elspeth deck. The card grants temporary boosts to your creatures while providing a modest life gain component, making it a functional if unremarkable limited role-player. Collectors view this primarily as a set completion piece rather than a sought-after card. Its uncommon rarity and lack of foil variants limit collector appeal. The Duel Decks series itself attracts casual players and budget-conscious builders more than serious collectors. Unless you're completing the full set or building a budget white deck, this card holds minimal collector value beyond its functional gameplay purpose.
