This intricate loop turns the seemingly harmless Shield Sphere into an engine of infinite potential. By sacrificing the Sphere to Thermopod for red mana and then sacrificing Salvager of Ruin to return that same Sphere to your hand, you set up a zero-mana historic spell casting of Shield Sphere. Every time you cast it, Teshar, Ancestor's Apostle triggers to pull Salvager of Ruin right back from your graveyard to the battlefield, ready to recycle the cycle. Thermopod's ability to turn any sacrificed creature into red mana fuels the loop indefinitely, giving you infinite sacrifice triggers, storm count, and red mana to flood the board and overwhelm your opponents.
