Omen Hawker

Retreat to Coralhelm

How it works

1. Activate Omen Hawker by tapping it, adding C that can only be spent to activate abilities.
2. Activate Meloku by paying 1 and returning a land from the battlefield to your hand, creating a 1/1 Illusion creature token.
3. Activate Patron of the Moon by paying 1, putting up to two land cards from your hand onto the battlefield.
4. When the land(s) enter, Retreat to Coralhelm triggers that many times, untapping Omen Hawker.
5. Repeat.
