Mikaeus, the Unhallowed + Blasting Station + Hovel Hurler

Mikaeus, the Unhallowed

Blasting Station

Hovel Hurler

How it works

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