This clever loop turns a simple act of devotion into an engine of endless energy, relying on Xenograft to weave every creature into the Merfolk tapestry so Judge of Currents can watch over the proceedings. When you tap Famished Paladin for mana using the granted ability from Cryptolith Rite, Judge of Currents triggers to grant you a life. That sudden burst of life immediately satisfies Famished Paladin's own untap condition, resetting the vampire so it can tap again right away. The result is an unbroken, self-sustaining loop that generates infinite colored mana and endless life.
