This ingenious loop transforms ordinary islands into veritable geysers of blue mana with the help of High Tide, which doubles every drop of blue mana your lands produce. To keep the engine running, Pemmin's Aura enlists its untap ability to repeatedly ready North Pole Patrol, whose own tap ability untaps your mana-producing Island so you can tap it over and over again. As the Patrol dances between tapping and untapping, North Pole Patrol can also leverage its tap ability to untap any other permanent you control, turning this self-sustaining loop into a factory for infinite mana of any type your other permanents can provide.
