Ashaya, Soul of the Wild + Rootpath Purifier + Murasa Rootgrazer + Intruder Alarm + Shield Sphere

Ashaya, Soul of the Wild

Rootpath Purifier

Murasa Rootgrazer

Intruder Alarm

Shield Sphere

How it works

1. Activate Murasa Rootgrazer's second ability by tapping it, returning Shield Sphere to your hand from the battlefield.
2. Cast Shield Sphere by paying 0.
3. When Shield Sphere enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat.
5. If you control another nontoken creature without summoning sickness, this combo nets infinite mana creatures you control can produce.

This fascinating loop turns your entire creature base into an engine of continuous untapping, fueled by the interplay between Ashaya, Soul of the Wild and Rootpath Purifier. Because Ashaya makes all your nontoken creatures into lands in addition to their types, and Rootpath Purifier ensures every land you control is basic, you can use Murasa Rootgrazer's second ability to bounce Shield Sphere to your hand. You then recast Shield Sphere for zero mana, triggering Intruder Alarm to untap all your creatures—including Murasa Rootgrazer—so you can repeat the process indefinitely.
