Cast Traveling Plague by paying 3, attaching it to another creature you control.
When Traveling Plague enters, Gremlin Tamer triggers, creating a creature token.
When the creature token enters, Blasting Station triggers, untapping Blasting Station.
Activate Blasting Station by sacrificing the creature Traveling Plague is attached to.
When the creature dies, Traveling Plague triggers, returning itself from your graveyard to the battlefield attached to the token created in step 2.
Repeat steps 2 and 3 one additional time.
Resolve the Blasting Station ability from step 4.
Repeat from step 4.
This loop relies on an endlessly recurring enchantment and a clever sacrifice engine to close out a game. By leveraging Gremlin Tamer’s eerie ability, every time Traveling Plague enters the battlefield attached to a new host, you spawn a fresh token. Meanwhile, Blasting Station provides the necessary sacrifice outlet to bin your enchanted creature—triggering Traveling Plague’s self-returning safety net so it can loop right back onto the newly minted token while simultaneously pelting your opponents with infinite damage.
