Ashaya, Soul of the Wild + Rootpath Purifier + Murasa Rootgrazer + Retreat to Coralhelm + Memnite

Ashaya, Soul of the Wild

Rootpath Purifier

Murasa Rootgrazer

Retreat to Coralhelm

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, Retreat to Coralhelm triggers, untapping Murasa Rootgrazer.
4. Repeat.

This ingenious engine turns free casting into an infinite loop by leveraging Ashaya, Soul of the Wild to treat your nontoken creatures like Memnite as Forest lands in addition to their other types. Rootpath Purifier ensures these creature-lands are recognized as basic lands, allowing Murasa Rootgrazer's second ability to target and bounce Memnite right back to your hand for zero mana. When you recast Memnite for free, Retreat to Coralhelm triggers its landfall ability to untap Murasa Rootgrazer, resetting the entire loop for infinite creature enters-the-battlefield events, leaves-the-battlefield events, landfall triggers, and storm count.
