The Warp (Exotic Orchard)

{t}: Add one mana of any color that a land an opponent controls could produce.

"The Warp is a strange and terrible place. You might
as well throw a traveller into a sea of sharks and tell him to swim home as send him through the Warp unprotected. Better it is not to let common man travel through the stars. Better still, let him not know such a thing is feasible."
