Ashaya, Soul of the Wild + Trenching Steed + Bumi, Eclectic Earthbender

Ashaya, Soul of the Wild

Trenching Steed

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 Trenching Steed 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 Trenching Steed ability.
7. Repeat from step 3.
