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

Ashaya, Soul of the Wild

Rootpath Purifier

Murasa Rootgrazer

Intruder Alarm

Memnite

How it works

1. Activate Murasa Rootgrazer's second ability by tapping it, returning Memnite to your hand from the battlefield.
2. Cast Memnite by paying 0.
3. When Memnite 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 clever loop turns the zero-mana Memnite into a one-man engine by exploiting a web of continuous transformations. Ashaya, Soul of the Wild turns your nontoken creatures into Forests, and Rootpath Purifier ensures that these creature-lands (and everything else) are treated as basic lands. This means Murasa Rootgrazer's second ability can scoop up Memnite back to your hand as a "basic land" you control, allowing you to recast it for free. Every time Memnite drops back onto the battlefield, Intruder Alarm triggers to untap all creatures—including Murasa Rootgrazer—readying the whole apparatus to repeat the cycle indefinitely.
