Patron of the Moon + Amulet of Vigor + Arid Archway

Patron of the Moon

Amulet of Vigor

Arid Archway

How it works

1. Activate Patron of the Moon by paying 1, putting Arid Archway from your hand onto the battlefield.
2. When Arid Archway enters the battlefield, it and Amulet of Vigor trigger.
3. Resolve the Amulet of Vigor trigger, untapping Arid Archway.
4. Activate Arid Archway by tapping it, adding CC.
5. Resolve the Arid Archway trigger from step 2, returning it from the battlefield to your hand.
6. Repeat.

This loop creates an engine of endless iteration by turning Arid Archway's self-bouncing drawback into an absolute advantage. With Amulet of Vigor on the board, the land neatly untaps the moment it drops, allowing you to tap it for double colorless mana before its entry trigger finishes returning it safely back to your hand. Patron of the Moon fuels this cycle by providing the cheap, repeatable {1} activation required to immediately drop Arid Archway right back onto the battlefield, sustaining the loop for infinite mana and landfall triggers.
