So you could get Emrakul out for 6 if you have every single type of card in the graveyard. As much fun taking another players turn or how funny that is, I've never liked that mechanic and it's stupid.
The wolf is cool, going to work very well with arlinn.
Coax from the Blind Eternitie for 3,, hmm I get it's intentions but I can take a spin on wordings. The sideboard is part of the game, if it isn't then why have it as part of the game. I can also see someone reaching into thier backpack, pulling out thier binder, finding that eldrazi, and putting it into thier hands. Now that's outside of the game.
They are cool cards non the less
