Ashaya, Soul of the Wild + Phantom Train + Toph, the Blind Bandit

Ashaya, Soul of the Wild

Phantom Train

Toph, the Blind Bandit

How it works

1. Cast Toph by paying its mana cost
2. When Toph enters, its earthbend ability triggers, causing it to earthbend itself as it is a Forest due to Ashaya.
3. Activate Phantom Train by sacrificing Toph
4. When Toph dies, it triggers, returning itself from your graveyard to the battlefield tapped.
5. When Toph enters, its earthbend ability triggers, causing it to earthbend itself as it is a Forest due to Ashaya.
6. Resolve the Phantom Train ability.
7. Repeat from step 3.
