Adagia, Windswept Bastion + Treachery + Gruul Turf

Adagia, Windswept Bastion

Treachery

Gruul Turf

How it works

1. Activate Gruul Turf and up to three other lands by tapping them, adding at least 4.
2. Activate Adagia by paying 3 and tapping it, creating a token copy of Treachery that is legendary attached to any creature.
3. If you control two legendary Treachery permanents, put one into your graveyard due to the legend rule.
4. The Treachery token's enter-the-battlefield ability triggers, untapping Adagia, Gruul Turf and up to three other lands.
5. Repeat.

This clever loop relies on the token-copying engine of Adagia, Windswept Bastion to continually exploit the enter-the-battlefield untap trigger of Treachery. By using your lands—including the self-bouncing Gruul Turf—to generate the mana required to activate Adagia's high-threshold ability, you can duplicate Treachery onto a creature over and over. Each newly created token enters and untaps Adagia, Gruul Turf, and your other tapped lands, letting you immediately harvest their mana again. The legend rule steps in to quietly clean up the excess legendary Treachery tokens as they appear, keeping your board clear while your lands stay perpetually fresh and ready to fuel the next iteration.
