The Master, Formed Anew + Blasting Station

The Master, Formed Anew

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing The Master.
2. When The Master dies, if it was a copy of the undying creature, its undying ability triggers, returning it from your graveyard to the battlefield as a copy of the persist creature with a +1/+1 counter on it.
3. Otherwise, if The Master was a copy of the persist creature, its persist ability triggers, returning it from your graveyard to the battlefield as a copy of the undying creature with a -1/-1 counter on it.
4. When The Master enters the battlefield, Blasting Station triggers, untapping Blasting Station.
5. Resolve the Blasting Station ability from step 1, dealing 1 damage to any target.
6. Repeat.
