Mikaeus, the Unhallowed + Blasting Station + Encumbered Reejerey

Mikaeus, the Unhallowed

Blasting Station

Encumbered Reejerey

How it works

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