How is this diamond team?

Great Diversity! However, Infernape has too many fire type moves. You can choose to give it Taunt or another type of move in place of Flamethrower and Fire Blast. Staraptor needs to get rid of Defog and Fly and in place of those U-Turn and Steel Wing. Vespiquen is just right. Gastrodon could get rid of Surf since Muddy Water is already there. May I suggest Hidden Power, and whatever the outcome, you may keep. Spiritomb is okay also, but Dream Eater may not heal as much as you want unless of course with Big Root attached. Embargo could be a good substitute. For Roserade, Sludge Bomb and Poison Jab are both Poison type moves. Get rid of Poison Jab so it can be a special sweeper. Synthesis could work very well on it.
