Mikaeus, the Unhallowed + Blasting Station + Brambleback Brute

Mikaeus, the Unhallowed

Blasting Station

Brambleback Brute

How it works

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