Can you please rate my pokemon team?

I think you are doing great so far, let's just say you're not behind. I like the different type combinations, but you will need to train a lot more for the elite 4. Venasuar is going to be your strongest et on your team for sure. Wigglytuff and marowak are good but neither are total powerhouses. I would at least have all your pokemon level 55 or above when you fight the elite 4, or you might find yourself in trouble when it comes time to face Agatha of the Elite 4.
