How it works

2. When Delif's Cone enters, Retreat to Emeria triggers, creating a 1/1 Kor Ally creature token.
3. When the Kor Ally enters, Haru triggers, earthbending Delif's Cone.
4. Activate Delif's Cone by tapping and sacrificing it.
5. Haru triggers, returning Delif's Cone from your graveyard to the battlefield.
6. Repeat steps 2 and 3 once.
7. Resolve the Delif's Cone ability from step 4.
8. Repeat from step 4.
