How it works

1. Cast Stalactite Dagger by paying 2.
2. When Stalactite Dagger enters, it triggers, creating a 1/1 Shapeshifter creature token with changeling.
3. When the Shapeshifter enters, Haru triggers, earthbending Stalactite Dagger, as it's a land due to Toph.
4. Activate Troubled Healer by sacrificing Stalactite Dagger.
5. When Stalactite Dagger dies, Haru triggers, returning Stalactite Dagger from your graveyard to the battlefield.
6. Repeat steps 2 and 3 once.
7. Resolve the Troubled Healer ability.
8. Repeat from step 4.
