Is my pokemon black team ready for victory road?

Yeah they are ready. It's not much of a challenge to get through Victory Road just annoying how all the Pokemon come out. X( Also if you keep going through the the Road you'll find a doctor that will heal you. And when you get to the top there will be a ranger that will say do you have the guts to slide down or something, go through the gates to where the Elite Four are first and then come back because if you slide down you will go back to the beginning. :P Also I would suggest that you train them though for the Elite Four. For a fifth Pokemon I would suggest Mienfoo maybe? You can find him in Victory Road.
