Guardians: Uprising is a 33-card "Hero Pack" expansion for Guardians that includes four new heroes — Atrivoxx, Chamber, Pandora, Nightshade — each with their own distinct set of cards and abilities. Each hero includes a full power deck and Ultimate card, which can be added to your collection and drafted into new Guardians decks. Additionally, these new heroes are the first to use the powerful Blast Damage ability, which can deal damage to multiple enemy heroes at once.
