After the coming rotation with Khans of Tarkir being released, will there be any way to remove from the battlefield a Darksteel Citadel that has been turned into a creature by Nissa, Worldwaker's first +1 ability?
It seems the me that being indestructible and also a land protect it from almost all removal, Devour Flesh in the current standard being the only obvious exception.
I'm looking for solutions in the soon-to-be Theros + Khans of Tarkir standard format.
