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.) Flying 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.
Pro Tip! 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. Yorion, Sky Nomad is banned in Modern.
