3. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability.
7. Repeat from step 3.
