Holding priority, cast Dualcaster Mage by paying its mana cost.
When Dualcaster Mage enters, it and Blasting Station trigger.
Resolve the Blasting Station trigger, untapping it.
Holding priority, activate Blasting Station by tapping it and sacrificing Dualcaster Mage.

This loop turns a simple graveyard resurrection into an endless cycle of arcane echoes and ballistic impacts. When you cast Dread Return and drop Dualcaster Mage into the mix with flash, the Mage's entry triggers its own spell-copying ability alongside Blasting Station's untap trigger. Blasting Station acts as the engine's catalyst, converting the constant stream of returning spellcasters into fatal damage by sacrificing Dualcaster Mage to untap itself, while the copied Dread Return continuously fishes the Mage right back out of the graveyard to do it all over again.
