Comprehensive Rules Glossary (August 7, 2020)

Companion
A keyword ability that allows a player to choose one creature card from outside the game as a companion if the restriction of that card’s companion ability is met. Once a player has chosen a companion, that player may pay C3 to put it into their hand once during the game. See rule 702.138, “Companion.”
Concede
To quit the game. Conceding a game immediately causes that player to leave that game and lose that game. See rule 104, “Ending the Game.”

Comprehensive Rules (August 7, 2020)

  • 702.138. Companion
    • 702.138a Companion is a keyword ability that functions outside the game. It’s written as “Companion—[Condition].” Before the game begins, you may reveal one card you own from outside the game with a companion ability whose condition is fulfilled by your starting deck. (See rule 103.2b.) Once during the game, any time you have priority and the stack is empty, but only during a main phase of your turn, you may pay C3 and put that card into your hand. This is a special action that doesn’t use the stack (see rule 116.2g). This is a change from previous rules.
    • 702.138b If a companion ability refers to your starting deck, it refers to your deck after you’ve set aside any sideboard cards. In a Commander game, this is also before you’ve set aside your commander.
    • 702.138c Once you take the special action and put the card with companion into your hand, it remains in the game until the game ends.
