Ashaya, Soul of the Wild + Phantom Train + Bumi, Eclectic Earthbender

Ashaya, Soul of the Wild

Phantom Train

Bumi, Eclectic Earthbender

How it works

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