Selvala, Heart of the Wilds + Slimefoot and Squee + Fires of Yavimaya + Phantom Train

Selvala, Heart of the Wilds

Slimefoot and Squee

Fires of Yavimaya

Phantom Train

How it works

1. Activate Selvala by paying and tapping it, adding at least 1.
2. Activate Phantom Train twice by sacrificing Selvala and Slimefoot and Squee.
3. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling, returning it and Selvala from your graveyard to the battlefield.
4. When Slimefoot and Squee enters the battlefield, it triggers, creating a 1/1 Saproling creature token.
5. Repeat.

This brilliant recursion loop relies on Selvala, Heart of the Wilds to convert our growing board state into a massive stream of mana, while Fires of Yavimaya grants the haste needed to keep our sacrificed pieces moving smoothly. Phantom Train acts as our sacrificial engine, gobbling up our key creatures and growing larger with each iteration. Finally, Slimefoot and Squee brings the whole machine together by using that generated mana and a freshly spawned Saproling token to pull both itself and Selvala right back out of the graveyard.
