Restricted is a keyword on player cards. A player cannot have more than two cards with the restricted keyword in play under their control at the same time. If a player ever controls more than two restricted cards in play, they must immediately choose and discard (from the restricted cards in play) until they have only two in play.
- Restricted cards with different names are still counted towards the two card limit in play.
- During deck building, unlike unique, there is no limitation on how many restricted cards you can have, as long as you obey the standard deck-building rules.
