This eccentric lock piece turns Lethal Vapors into an absolute, inescapable trap for any creature trying to enter the battlefield. The genius here lies in Mycosynth Lattice, which acts as the ultimate enabler by turning Lethal Vapors—and every other permanent on the board—into an artifact. From there, Null Rod steps in to shut down all activated abilities of artifacts, meaning no player can ever pull the ripcord to destroy Lethal Vapors or skip their turn. The result is a total creature sweep and a bizarre permanent standstill that leaves the board locked down tight.
