Kaela, Shepherd of the Lands

Reach

{g/w}, {t}: Untap a target land you control. If that land is a forest, you may add one mana of any color.

Whenever a land enters the battlefield under your control, you may search your library for a land card and put it into play tapped.

"I see faith in the branches, roots, rivers, and soil. Whether it feels pain or endures sorrow, the land’s beliefs should never be dismissed."
