A really simple card Wizards hasn't made yet and considering the cost of Tormod's Crypt this CMC is probably right on the money. Any thoughts?

I've always been a bit weirded by how all over the map exiling cards in graveyards is. I guess it's the 'graveyard matters' sets. Sometimes Wizards doesn't want you to monkey with your opponent's graveyard unless they are making great strains to interact with the opponent (see Odyssey block), and sometimes the graveyard effects are a strong secondary theme, and Wizards would really like there to be some super-effecient hosers to make sure the sub-theme doesn't spiral out of control (see Innistrad).

This is certainly strong, but I guess you got a good reason for it with this set, since exiling matters. I don't think I can give any more advice than that when it comes to the cost, though. I get the impression that the correct answer would be "whatever is the most fun right now". If you want it to be easy to exile whole graveyards in a go, this is on the money. If you want players to work for it, I could see you charging up to more for this. Either way would probably be fine.

The name, regrettably, has been taken however. Everyone Forgets Homelands... for good reason.

Arrgh. Name taken... The name is so perfect for the creative flavor behind this card that I'm not going to change it until I can think of something better.

Cost seems fine to me, unless playtesting finds it's too good.

Yeah, a bunch of really good names were taken by Homelands and The Dark.
