ok so that is my team, and since im going to be in the video game showdown i will only be able to go to level 50 with my whole team and i will not be able to use the same iteam on two pokemon. also the format of battle is 2v2 so i need some suggestions on if this is a good team for doubles and which should be paired with which. thanks for all your help.
