Activate Blasting Station by tapping it and sacrificing Vorapede

Activate Blasting Station by tapping it and sacrificing Vorapede
When Vorapede dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
When Vorapede enters, Blasting Station triggers, untapping Blasting Station.
Resolve the Blasting Station abilities from step 1 and 4.
Repeat.
This loop transforms Blasting Station into an infinite damage machine by continuously recycling Vorapede through its graveyard triggers. Because Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight is active on your battlefield, its back face grants persist to your other nontoken creatures, neatly balancing out Vorapede's native undying ability. When Vorapede dies with a +1/+1 counter, it returns with a -1/+1 counter neutralizer setup, and when it dies *that* time, persist brings it back with a -1/-1 counter, allowing undying to trigger anew. Each iteration feeds right back into Blasting Station's untap trigger, letting you blast your opponents to zero without ever running out of ammunition.
