Purity is a gameplay mechanic in Infinity Wars, which limits which cards can be used in specific decks.


Every Card in Infinity Wars has a certain level of purity, with the exception of Factionless cards. The Purity of a card determines whether or not it can be used in a deck, based on its Commanders.

To use any card from a particular Faction (excluding Factionless) in a deck, the deck will always require at least one Commander from that Faction. If two or three Faction symbols appear on a card, the deck will require that many Commanders from that particular faction to be legal.
