Melira, Sylvok Outcast + Blasting Station + Safehold Elite

Melira, Sylvok Outcast

Blasting Station

Safehold Elite

How it works

1. Activate Blasting Station by tapping it and sacrificing Safehold Elite.
2. When Safehold Elite 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 Safehold Elite enters, Blasting Station triggers, untapping Blasting Station
4. Resolve the Blasting Station ability from step 1
5. Repeat.
