Ascension: Immortal Heroes

Ascension: Immortal Heroes does double duty: it is the second set in the Storm of Souls story arc and a complete two-player game by itself. The deckbuilding is the familiar Ascension kind. A shared row of cards sits in the middle, and each turn you spend what you have to recruit heroes and constructs or to defeat monsters, and your purchases join your growing deck. Both acquired cards and defeated creatures earn points. The new Soul Gem cards represent trapped souls of past heroes whose power you can wield in the effort to stop the rebel godling Kythis from reaching godhood. Fast, familiar and ideal for a duel.
