Evolving Wilds

{t}, Sacrifice Evolving Wilds: Search your
library for a basic land card, put it onto
the battlefield tapped, then shuffle.

"The wilds are unpredictable. Rivers change
course, trees shuffle and bend, rocks split and
scurry. But mark my words, traveler—the
main thing that'll change out there is you."
—Sturwynn, Boundary Lands ranger
