Melira, Sylvok Outcast + Blasting Station + Obstinate Gargoyle

Melira, Sylvok Outcast

Blasting Station

Obstinate Gargoyle

How it works

1. Activate Blasting Station by tapping it and sacrificing Obstinate Gargoyle.
2. When Obstinate Gargoyle dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. When Obstinate Gargoyle enters, Blasting Station triggers, untapping Blasting Station
4. Resolve the Blasting Station ability from step 1
5. Repeat.
