Giratina VSTAR (Lost Origin) is a similar matchup, but you can always use Regieleki (Evolving Skies) to snipe a Giratina V (Lost Origin) on the Bench and sweep up with Regidrago (Evolving Skies) for the remaining 240 damage
As such, Id be remiss to not mention them, especially since I play them both
The Commander variant requires exactly one hundred cards, so Yorion can never be your chosen companion in a Commander game
(Until your next turn, that creature can't attack or block and its activated abilities can't be activated.) If a card has no mana cost, its escape cost is an unpayable cost, so you can't cast it for that cost
The roll number determines how many cards are exiled and can get played that turn
This precon only has 2 commander options: Sauron, Lord of the Rings or Saruman, the White Hand
