Challenge Deck
A challenge deck is preconstructed theme deck with special cards (like elite creatures and sorceries). It is a self-running deck with its own set of rules. The cards have special backs, which means they aren’t counted as regular magic cards. When playing against the challenge deck players may use Hero cards, which act like a Vanguard (or Magic online Avatar).
There are three challenge decks:
- Face the Hydra (Theros)
- TBA (Born of the Gods)
- TBA (Journey into Nyx)
