Blasting Station + Restless Apparition + Hardened Academic

Blasting Station

Restless Apparition

Hardened Academic

How it works

1. Activate Blasting Station by tapping it and sacrificing Restless Apparition.
2. When Restless Apparition dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Hardened Academic and Blasting Station trigger.
4. Resolve the Hardened Academic trigger, putting a +1/+1 counter on Restless Apparition.
5. Resolve the Blasting Station trigger, untapping it.
6. Resolve the Blasting Station ability from step 1.
7. Repeat.

This clever loop turns the self-recurring nature of Restless Apparition into a lethal engine by using Blasting Station as both the sacrifice outlet and the damage dealer. Because Blasting Station untaps whenever a creature enters, it resets itself with every iteration of the cycle while effortlessly pelting your opponents. The true secret to sustaining this loop indefinitely is Hardened Academic, whose static-like triggered ability watches cards leave the graveyard and promptly cancels out the creature's persist penalty with a +1/+1 counter.
