2. Holding priority, activate Circle of Dreams Druid by tapping it, adding at least six .
3. Activate Emiel by paying 3, blinking Bristling Hydra.
4. Bristling Hydra enters the battlefield, causing you to get EEE.
5. Repeat from step 3 one additional time.
6. Resolve the Lightning Runner ability from step 1, causing you to get EE, then pay eight E to untap all creatures you control, and to get an additional combat phase after this one.
