MAGIC: THE GATHERING
|Edition:||Ikoria: Lair of Behemoths|
|Type:||Legendary Creature - Bird Serpent|
Companion - Your starting deck contains at least twenty cards more than the minimum deck size. (If this card is your chosen companion, you may cast it once from outside the game.)
When Yorion enters the battlefield, exile any number of other nonland permanents you own and control. Return those cards to the battlefield at the beginning of the next end step.
Commander has a fixed deck size, so unfortunately, Yorion cannot be your companion in Commander. However, the sheer value Yorion provides in other formats makes playing 20 extra cards well worth it.
