Beanith: I take it back Razorlash Transmogrant, all is forgiven
Its one thing for a combo to win a game and end it, but the worst banned cards will stop your opponents from doing anything from early in the game (think about cheating out a Sundering Titan on turn 1), but wont let you win for a long time
So, a card like Spectral Procession creates three 1/1 spirit tokens with flying and those tokens add nothing to devotion
Plus, if you dont end up casting the card you exiled, then you at least get to deal 2 damage to each opponent
Thanks to having four opponents, in Commander games, Faerie Mastermind can ideally provide four times the draw
Not only do they help you find your silver bullets when the situation calls for them, but they also let you trim down on cards your running for the sake of redundancy
