Zhalfirin Pathfinder

When Zhalfirin Pathfinder enters the battlefield,
you may search your library for three nonbasic
land cards with different names, reveal them,
then exile them face down in a random order.
Shuffle your library afterwards.
When Zhalfirin Pathfinder leaves the battlefield,
you may put up to one card exiled with it this
game from your exile zone on top of your library.
