This charming loop lets you flood the board with an endless army by turning Patrol Signaler into a one-man manufacturing plant. To pull this off, equip Patrol Signaler with Paradise Mantle so it gains the ability to tap for mana, which Mana Reflection instantly doubles to yield two mana of any color whenever you tap it. Because Patrol Signaler's ability costs only one white mana to activate and untap itself using the untap symbol, the doubled mana from tapping pays for the activation cost with mana to spare, leaving you with infinite creature tokens and infinite creature ETB triggers.
