This loop transforms Marina Vendrell into a rapid-fire room-flipping engine by taking advantage of Thornbite Staff, which equips to the Shaman Marina and untaps her whenever a creature dies. By repeatedly locking and unlocking Spiked Corridor // Torture Pit, Marina floods the board with Devil tokens that fuel Blasting Station's sacrifice outlet. Each sacrifice triggers the dying Devils to deal damage while simultaneously feeding Thornbite Staff's untap trigger back into Marina, sustaining an endless cycle of explosions.
