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

Ashaya, Soul of the Wild

Rootpath Purifier

Murasa Rootgrazer

Intruder Alarm

Ornithopter

How it works

1. Activate Murasa Rootgrazer's second ability by tapping it, returning Ornithopter to your hand from the battlefield.
2. Cast Ornithopter by paying 0.
3. When Ornithopter 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 engine transforms your entire creature base into a self-sustaining web of mana and motion, anchored entirely by Ashaya, Soul of the Wild turning every nontoken creature you control into a Forest land in addition to their other types. Rootpath Purifier ensures all those land types—and your library's land cards—are explicitly basic, allowing Murasa Rootgrazer to effortlessly bounce and replay your free artifacts like Ornithopter. Every time Ornithopter re-enters the battlefield, Intruder Alarm triggers to untap all creatures, resetting Murasa Rootgrazer to tap once more and repeat the loop.
