Mikaeus, the Unhallowed + Blasting Station + Moonlit Lamenter

Mikaeus, the Unhallowed

Blasting Station

Moonlit Lamenter

How it works

1. Activate Blasting Station by tapping it and sacrificing Moonlit Lamenter.
2. When Moonlit Lamenter dies, its undying ability triggers, returning it from your graveyard to the battlefield without a +1/+1 counter on it due to its replacement effect.
3. When Moonlit Lamenter enters, Blasting Station triggers, untapping Blasting Station.
4. Resolve the Blasting Station ability from step 1
5. Repeat.
