This brilliant engine transforms the humble Island into an infinite mana and landfall generator, using High Tide to supercharge your blue mana production every time a land is tapped. As you cast Mythos of Illuna, the back face of your Invasion of Arcavios // Invocation of the Founders steps in to multiply your spells, while Gogo, Master of Mimicry goes to work duplicating those triggers to keep the loop spinning. Every time a fresh Island token enters the battlefield, Retreat to Coralhelm triggers to untap Gogo, allowing you to tap your new land for massive mana and repeat the entire sequence indefinitely.
