Maybe. But not with substitute. Plus, im pretty sure the meta game is in triple battles. A strong psychic pokemon can stop it. Plus, many pokemon can use fire moves. Whether its flamethrower, or nitro charge, they can power up chanderras fire moves. Besides, machamp are slow and can be destroyed by those who fear it with a simple psychic. Too bad it didnt get levitate. Would have been great with groudon. It can hit nearly anything with neutral damage. If nitro charge was special, it would dominate. Needs some teamates to outspeed weavile. And overpower tyranitar.
