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.
Sadly, Yorion can't be your companion in Commander or Brawl because those formats have fixed deck sizes. But Standard and Pioneer players are more than willing to rustle up 20 extra cards to play it!
