Indestructible
As long as your devotion to green and white is less than seven, Karametra isn't a creature.
Whenever you cast a creature spell, you may search your library for a Forest or Plains card, put it onto the battlefield tapped, then shuffle.
Karametra turns every creature you cast into a free, tapped basic land, letting you ramp explosively and snowball into huge threats. You flood the board with creatures (especially ETB value and blink targets), accelerate your land count well beyond curve, then close with overwhelming board presence or a landfall/X-spell payoff.
Lean harder into cheap, repeatable creature recursion and blink (Eternal Witness, Restoration Angel, Conjurer's Closet) to maximize triggers, and add bounce-loop engines like Cloudstone Curio for near-infinite ramp. Tighten the curve with efficient mana dorks and tutors (Green Sun's Zenith, Worldly Tutor) and add fast finishers like Craterhoof Behemoth and Finale of Devastation. Improve interaction with Heroic Intervention and Teferi's Protection so your snowball doesn't get blown out by a single wrath.
