That is mostly starters and a crappy type coverage too.
Fennekin and Chandelure are weak to water
Vivillion and Serperior are weak to fire
Empoleon, Blastoise and Vivillion weak to electricity
Empoleon can easily be taken down by a solid fighting as well.
Chandelure being part ghost type is also weak to dark types and ghost types
Empoleon has a ground weakness as does Fennekin
Vivillion is also weak to rock, ice and flying.
The water starters are weak to grass types too.
Your team really is not the best when it comes to type coverage imo.
I would have gone with a team that could cover all of those weaknesses very well. Also Chandelure is weak to rock and ground types as well.
