This Vintage-legal engine turns your resources into an infinite loop of destruction, fueled seamlessly by Mana Crypt providing the initial mana to jump-start the cycle. Thopter Foundry sacrifices that very Mana Crypt to forge a 1/1 Thopter token while padding your life total, which in turn triggers Blasting Station to ready itself for the kill. When you use Blasting Station to sacrifice the Thopter, the resulting death triggers Salvaging Station to untap, allowing it to fish the fallen Mana Crypt right back out of your graveyard and onto the battlefield.
