Swooping Skyfolk

Flying, first strike
Expedition—Whenever Swooping Skyfolk
attacks, you may search your library for a land
card, put it into your graveyard, then shuffle. If
you do, return up to one target creature you
control to your hand.
Not even the Skyfolk themselves know whether they
are a product of the Planecleanser fallout or if they
existed in the Beforeworld.
