This cunning loop centers around Marina Vendrell wielding a Thornbite Staff, taking advantage of her ability to continually lock and unlock a Room to flood the board with fodder. By unlocking Spiked Corridor // Torture Pit, you generate a fresh supply of 1/1 Devil creature tokens to fuel Goblin Bombardment. Each time a Devil is sacrificed, Thornbite Staff’s trigger untaps Marina so she can reset the room, allowing you to repeat the cycle endlessly and weaponize the sacrifices for infinite damage.
