Shepherd of Guardian's Grove

Treefolk creatures you control get +2/+2 and have vigilance.

Whenever a treefolk you control dies, you may pay
{3}{g}. If you do, search your library for a basic land, reveal it, and put it onto the battlefield tapped, then shuffle.

{1}{g}: Transform Shepherd of Guardian's Grove. Activate this ability only any time you could
cast a sorcery.
