Blasting Station + Warden of the Grove

Blasting Station

Warden of the Grove

How it works

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