Stalwart Successor + Blasting Station

Stalwart Successor

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing the creature with persist.
2. When that creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When that creature enters, Blasting Station and Stalwart Successor trigger.
4. Resolve the Blasting Station trigger, untapping it.
5. Resolve the Stalwart Successor trigger, putting a +1/+1 counter on the persist creature.
6. Remove a +1/+1 and a -1/-1 counter from that creature as a state-based action.
7. Resolve the Blasting Station ability from step 1
8. Repeat.
