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

Ashaya, Soul of the Wild

Rootpath Purifier

Murasa Rootgrazer

Intruder Alarm

Phyrexian Walker

How it works

1. Activate Murasa Rootgrazer's second ability by tapping it, returning Phyrexian Walker to your hand from the battlefield.
2. Cast Phyrexian Walker by paying 0.
3. When Phyrexian Walker 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 ingenious loop turns the simple zero-mana drop of Phyrexian Walker into a perpetual motion machine, fueled by Murasa Rootgrazer's ability to bounce a basic land back to your hand. Thanks to Ashaya, Soul of the Wild, every single nontoken creature you control is secretly a Forest land in addition to its other types, meaning Murasa Rootgrazer can actually target and bounce the Phyrexian Walker itself! Rootpath Purifier quietly ensures all these moving pieces qualify as basic, so everything synergizes smoothly. Every time you recast the Walker for free, Intruder Alarm notices the creature entering the battlefield and untaps all your creatures—including Murasa Rootgrazer—allowing you to repeat the cycle infinitely for boundless landfall triggers, creature entries, and a massive storm count.
