Rulings (18)
Your minimum deck size is forty cards for Limited events (such as Booster Draft and Sealed Deck) and sixty cards for Constructed events (such as Standard or casual freeform play). Certain variants may have other minimums. The Commander variant requires exactly one hundred cards, so Yorion can never be your chosen companion in a Commander game.

If you reveal a companion outside the game, for as long as it remains there, you may pay any time you could cast a sorcery (that is, you have priority during your main phase and the stack is empty). Once you do, you put it into your hand and behaves like any other card you've brought into the game. For example, if it's discard, countered, or destroyed, it's put into your graveyard, remaining in the game. This is a change from previous rules.

The requirements of the companion ability apply only to your starting deck. They do not apply to your sideboard.

Your companion begins the game outside the game. In tournament play, this means your sideboard. In casual play, it's simply a card you own that's not in your starting deck.
