Is this a good pokemon team?? plz rate it?

It seems like a pretty good team. The natures, I don't know what's increased or decreased in them since I didn't memorize them, but I know Adamant increases Attack so you did good with Scizor and Infernape. Tyranitar is a slow Pokemon, and Jolly Nature increases Speed and Reduces SP.ATK, I would've gone for an Attack increasing nature. I think Bold Nature is nutural isn't it? If it's not I hope another answerer corrects me on this. Because Zapdos is a Special Attacker, so I would've gone with Mild Nature, same with Vaporeon. Roserade seems OK. The problem I see with this team is that it's too offensive. You need to put some Defense in it, while your team has good offense, the team needs defense. Like a Slowbro/Slowking, or a Mantine. Now if I'm wrong, I hope someone will correct me. I'd rate this a 7.
