This intricate loop turns the board into a powerhouse of green mana by weaving together Ashaya, Soul of the Wild's passive magic with a clever self-returning creature. Because Ashaya makes every nontoken creature a Forest land, Scryb Ranger's ability can target itself as a "Forest" to bounce back to your hand and untap Leafkin Avenger. Then, you simply recast the Ranger for a modest mana investment, leaving Leafkin Avenger's tap ability—fueled by the combined power of your creatures—free to generate a net surplus of green mana.
