Mikaeus, the Unhallowed + Blasting Station + Creakwood Safewright

Mikaeus, the Unhallowed

Blasting Station

Creakwood Safewright

How it works

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