This brilliant loop transforms Yurlok of Scorch Thrash into a lethal weapon by feeding his own mana-production mechanic back into a devastating offensive engine. With Agatha's Soul Cauldron having exiled Hateflayer to grant its activated ability to a +1/+1 counter-bearing Yurlok, and Biomancer's Familiar discounting that ability's cost, Yurlok gains the remarkable capability to repeatedly untap and deal damage equal to its power. Because Yurlok of Scorch Thrash's own activated ability adds massive amounts of mana to every player's pool—while uniquely turning unspent mana into life loss via its own static ability—the combination effortlessly funnels infinite damage and life loss to your opponents alongside infinite mana.
