I need help choosing the last Pokemon for my party. Currently I have and plan on using Serperior, Simipour, Krookodile, and Archeops. I also have a Tranquill and Munna in my party right now. I want to choose two out of three from Axew, Litwick, and Tynamo. I know Litwick and Tynamo are kind of weak to start off but I know that their evolutions are really strong. Suggestions?
