Activate Blasting Station by tapping it and sacrificing Highspire Artisan.
When Highspire Artisan dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
When Highspire Artisan enters, its fabricate ability and Blasting Station trigger.
Resolve the Highspire Artisan ability, putting a +1/+1 counter on it.
Resolve the Blasting Station trigger, untapping it.
Resolve the Blasting Station ability from step 1.
Repeat.
This clever loop centers around Blasting Station as both the sacrificial outlet and the damage dealer, weaponizing Highspire Artisan's recursive lifecycle to burn down the opposition. While Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight sits on your board, its back face grants your nontoken creatures persist, ensuring that when Highspire Artisan hits the graveyard, it immediately crawls back with a -1/-1 counter. The genius of the interaction lies in Highspire Artisan's fabricate trigger; by choosing to put a +1/+1 counter on it upon re-entry, state-based actions cause that counter and the existing -1/-1 counter to annihilate each other, leaving the artisan completely clean and ready to be sacrificed to Blasting Station all over again.
