Ashaya, Soul of the Wild + Trenching Steed + Toph, the Blind Bandit

Ashaya, Soul of the Wild

Trenching Steed

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