Canyon Lurkers

Any time you have priority, you may turn the face-down creature face up by revealing what its morph cost is and paying that cost. This is a special action. It doesn’t use the stack and can’t be responded to. Only a face-down permanent can be turned face up this way; a face-down spell cannot.

A permanent that turns face up or face down changes characteristics but is otherwise the same permanent. Spells and abilities that were targeting that permanent, as well as Auras and Equipment that were attached to the permanent, aren’t affected.

At any time, you can look at a face-down spell or permanent you control. You can’t look at face-down spells or permanents you don’t control unless an effect instructs you to do so.
