dragon commander decks mtg Update - Mono Red Tribal with Inferno of the Star Mounts - Cycles Gaming Not to mention 7 power and 7 toughness combined with flying. The Ur-Dragon EDH Deck |

So it's not that unbalanced in my experience, but the opportunity to draft a dud deck is greater than most other Standard sets

Legendary Creature - Shaman Cat Silverback Elder Whenever you cast a creature spell, choose one Destroy target artifact or enchantment

Often in EDH you'll just want a 1-mana cantrip to fuel some storm or Izzet shenanigans

Legendary Creature - Beast Elemental Dinosaur Mission Briefing Surveil 2, then choose an instant or sorcery card in your graveyard

While I'm not sure this is enough to make the card main-deckable in the current meta, the bar for cards that replace themselves is pretty low
