Purge
Marked text is printed in red in LRR v2.0 (new or changed with Prophecy of Kings)
Purge is a cost that permanently removes a component from the game. If an ability requires that its component is purged, that component can only be used once per game.
If an ability instructs a player to purge a component, that component is removed from the game and returned to the box.
Purged components cannot be used or otherwise returned to the game by any means.
When a player is intructed to purge a component, that component is purged even if its ability was only partially resolved.
