Activate Detective's Satchel by tapping it, creating a 1/1 Thopter artifact creature token.
When the Thopter enters, Blasting Station triggers, untapping Blasting Station.
Activate Blasting Station by tapping it and sacrificing the Thopter.
When the Thopter dies, Dross Scorpion triggers, untapping Detective's Satchel.
Resolve the Blasting Station ability.
Repeat.
This clever loop sets up an endless cycle of artifact creation and destruction by turning the mechanical synergy between Blasting Station and Dross Scorpion into a lethal engine. You start by using Detective's Satchel to manufacture a Thopter token, which immediately tickles Blasting Station's entry trigger to keep the station primed and ready. Sacrificing that very same Thopter to Blasting Station deals a point of damage to any target, and its death triggers Dross Scorpion to untap Detective's Satchel so the whole process can begin anew.
