Emrakul,Devourer of Worlds

Flying, protection from colored spells.
When Emrakul attacks, turn up to five lands into wastes. When all lands are wastes exile all other permanents.
Lands you control are wastes in addition to their other types and have "{t}: Add one mana of any color to your mana pool."
You may pay {w}{u}{b}{r}{g} for Eldrazi spells.
This is what the edge of eternity looks like.
