Meloku the Clouded Mirror

Retreat to Coralhelm

Llanowar Scout

How it works

1. Activate Llanowar Scout by tapping it, putting the land from your hand onto the battlefield.
2. When the land enters the battlefield, Retreat to Coralhelm triggers, untapping Llanowar Scout.
3. Activate the land by tapping it, adding at least 1.
4. Activate Meloku by paying 1 and returning the land from the battlefield to your hand, creating a 1/1 Illusion creature token.
5. Repeat.
