Selvala, Heart of the Wilds + Slimefoot and Squee + Temur Ascendancy + Phantom Train

Selvala, Heart of the Wilds

Slimefoot and Squee

Temur Ascendancy

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 clever loop centers around Slimefoot and Squee's ability to pull itself and another creature straight from the graveyard, fueled by the massive mana-producing potential of Selvala, Heart of the Wilds. To get the engine started, Phantom Train plays a crucial sacrificial role by sending both legends to the graveyard, while also growing larger with +1/+1 counters as it turns into a creature. Meanwhile, Temur Ascendancy and Selvala, Heart of the Wilds happily watch the parade of entering creatures to trigger their card-drawing abilities, turning an infinite loop of sacrifices and returns into a seemingly unstoppable advantage.
