This cunning loop transforms your entire creature base into a wellspring of infinite resources, brilliantly anchored by Ashaya, Soul of the Wild turning every nontoken creature you control into a Forest. Because they are now lands, you can use Scryb Ranger's ability to bounce itself by returning *any* of those creatures to your hand, which in turn untaps Yurlok of Scorch Thrash. With Yurlok freshly untappable, you tap it again to flood all players with black, red, and green mana, which fuels the mana needed to endlessly recast Scryb Ranger and repeat the cycle. Finally, Yurlok of Scorch Thrash's passive static ability ensures that any unspent mana left floating from these massive infusions ruthlessly drains your opponents' life totals into oblivion.
