This ingenious loop turns Kor Skyfisher into a self-returning engine by leveraging cost reducers to eliminate its mana requirement entirely. With Helm of Awakening lowering generic costs and Defiler of Faith discounting the remaining white mana in exchange for life, you can repeatedly cast the Kor Skyfisher for free while Defiler of Faith rewards each casting with a fresh 1/1 Soldier token. Every time one of those tokens enters the battlefield, Hinterland Sanctifier triggers to replenish your life total, easily offsetting the life paid to the Defiler. Finally, when Kor Skyfisher resolves and forces you to bounce a permanent, it simply picks itself back up into your hand, ready to start the cycle anew for endless triggers and tokens.
