What is better with Baby Volcanion is that he can take care of himself, - has strong attacks, good hp for non-EX while Camerupt has a 3 energy 60DMG attack, so if I end up with Camerupt it will become harder to damage the opponent.I personally would try both ways before doing anything else with the deck. That way you can decide which works for you and which would win more games. You could also use Fisherman to Steam Up for more and have energy to attack in your hand, ready to go.
