Diamond In The Rough

As long as you control Black Stone, Blue Stone,
Green Stone, White Stone, and Red Stone; When
Diamond In The Rough Is cast, you may create a
token that is a copy of Emrakul, the Aeons Torn.
For the rest of the game, treat this token as
though it isn't a token, and that it has mana cost {0}. You may only have one copy of Diamond In
The Rough in your deck.
