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 Yahenni 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 Yahenni ability.
8. Repeat from step 4.
