Patron of the Moon + Cloudstone Curio + Tiller Engine

Patron of the Moon

Cloudstone Curio

Tiller Engine

How it works

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

This ingenious loop is orchestrated by Patron of the Moon, whose active ability floods the battlefield with two lands from your hand for just one mana. As those lands enter the battlefield tapped, Tiller Engine immediately untaps them, allowing you to tap them for mana in response to everything else happening. Meanwhile, Cloudstone Curio sees the lands enter and triggers to bounce them right back to your hand, replenishing your hand so Patron of the Moon can send them right back down again. Together, this creates a self-sustaining cycle that generates infinite mana from your lands and boundless landfall triggers.
