Gogo, Master of Mimicry

Invasion of Vryn // Overloaded Mage-Ring

High Tide

Retreat to Coralhelm

Relm's Sketching

How it works

1. Cast High Tide by paying .
2. Cast Relm's Sketching by paying its mana cost, targeting an Island you control.
3. Holding priority, activate Overloaded Mage-Ring by paying 1, tapping and sacrificing it, targeting the Relm's Sketching spell.
4. Holding priority, activate Gogo by paying 2 and tapping it, copying the Overloaded Mage-Ring ability, targeting the Relm's Sketching spell.
5. Resolve the copy of Overloaded Mage-Ring's ability, copying the Relm's Sketching spell, targeting an Island you control that enters the battlefield untapped.
6. Resolve the copy of Relm's Sketching, creating a token copy of the targeted Island.
7. When the Island token enters, Retreat to Coralhelm triggers, untapping Gogo.
8. Activate the Island token by tapping it, adding .
9. High Tide triggers, adding .
10. Repeat from step 4.

This brilliant loop transforms simple land drops into an unstoppable engine, supercharged by High Tide to ensure you never run short on blue mana. At the heart of the setup is Relm's Sketching, which is continuously duplicated by sacrificing Invasion of Vryn // Overloaded Mage-Ring and copying that sacrifice ability with Gogo, Master of Mimicry. Every time a fresh token copy of an Island enters the battlefield, Retreat to Coralhelm triggers to untap Gogo, allowing you to feed the loop over and over again.
