Activate Blasting Station by tapping it and sacrificing Elegant Edgecrafters.
When Elegant Edgecrafters dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
When Elegant Edgecrafters enters, its fabricate ability and Blasting Station trigger.
Resolve the Elegant Edgecrafters trigger, putting a +1/+1 counter on it.
Resolve the Blasting Station trigger, untapping it.
Resolve the Blasting Station ability from step 1.
Repeat.
This loop turns a simple sacrifice outlet into a lethal engine by leveraging the recursive power of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight. While Isilu grants your nontoken creatures persist, Blasting Station provides the sacrificial fodder and the direct damage needed to close out the game. When you feed Elegant Edgecrafters to the Station, its persist ability brings it right back with a -1/+1 counter cancellation system—or in this case, a +1/+1 counter from its fabricate ability—ensuring Blasting Station untaps to repeat the cycle infinitely.
