Mikaeus, the Unhallowed + Blasting Station + Bristlebane Battler

Mikaeus, the Unhallowed

Blasting Station

Bristlebane Battler

How it works

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