Patron of the Moon + Cloudstone Curio + Archelos, Lagoon Mystic

Patron of the Moon

Cloudstone Curio

Archelos, Lagoon Mystic

How it works

1. Activate Patron of the Moon by paying 1, putting two nonartifact lands from your hand onto the battlefield untapped due to Archelos.
2. When the lands enter, Cloudstone Curio triggers twice.
3. Holding priority, activate the lands by tapping them, adding at least 1.
4. Resolve both Cloudstone Curio triggers, returning the lands from the battlefield to your hand.
5. Repeat.

This clever loop centers around Patron of the Moon's active ability, which allows you to dump lands directly from your hand onto the battlefield for just one mana. Archelos, Lagoon Mystic plays a vital foundational role here as a static enabler: while it is untapped, it ensures those incoming lands enter the battlefield *untapped*, allowing you to immediately tap them for mana before bouncing them back to your hand. Cloudstone Curio harnesses this entry by triggering whenever those nonartifact lands arrive, letting you return them to your hand to fuel the entire cycle over and over again.
