## Official Rulings
- *(2020-04-17)* If a card in a player's deck or a permanent on the battlefield has {X} in its mana cost, X is considered to be 0.
- *(2020-04-17)* The requirements of the companion ability apply only to your starting deck. They do not apply to your sideboard.
- *(2020-04-17)* The companion's other abilities apply only if the creature is on the battlefield. They have no effect while the companion is outside the game.
- *(2020-04-17)* The mana value of a token that isn't a copy of another object is 0. A token that is a copy of another object has the same mana cost as that object.
- *(2020-04-17)* Before shuffling your deck to become your library, you may reveal one card from outside the game to be your companion if your starting deck meets the requirements of the companion ability. You can't reveal more than one. It remains revealed outside the game as the game begins.
- *(2020-04-17)* If more than one player wishes to reveal a companion, the starting player does so first, and players proceed in turn order. Once a player has chosen not to reveal a companion, that player can't change their mind.
