Eye of the Lake

{t}:Exile Eye of the Lake, then return it to the battlefield during your next end step.
Serenity: If you control no creatures, as long as
Eye of the Lake is exiled, you may gain control of
target noncreature permanent for as long as Eye
of the Lake remains exiled. When Eye of the Lake
returns to the battlefield, that permanent is sent
to its owner's hand.
