Magistrate of the Wilds

(You may cast an instant creature as though it has
flash.)
Repurpose {1}{g} (You may cast this spell for its repurpose cost. If you do, it's not a creature. Replace
all instances of "enters the battlefield" with "resolves.")
When Magistrate of the Wilds enters the battlefield, search your library for a basic land
card, put it onto the battlefield tapped, then
shuffle your library.
