Your team is great! id give it a 9 /10, just because i think
your team might need a supporter or a healer because none of your
pokemon can heal. id say give avalugg recover instead of stone edge
because of its low accuracy. If your going to use zoroark then you probable want chadalure
to be in last because the opponent might want to use a dark type move on it and zoroark is not affected when hit with dark.
oh god.your ferrothorn is a really nasty pokemon with rocky helmet and those moves. it got me so angry that i was fighting a person in wi-fi and he was using the same ferronthorn, and i didnt have a fire type:(. But overall your teams awesome, good job:)

Ok thanks for the advice :) ferrothorn used to always make me mad so I figured I had to have him on my team!

Hi! i would like to make some comments. hope you dont mind.

1. i think it is not a good idea to run a nasty plot set to zoroark when you're going to use a choice item as you would need to switch out.
2. half of the team would be badly affected by stealth rocks. so i suggest a Rapid Spinner.
3. your chandelure has an offensive set. i suggest choice scarf so it wont be outsped easily but other choice scarf users.

that's all for now. feel free to correct me though. Thanks :)

the teams ok but if u ran into a mega charizard ur team is as good as dead no doubt due to speed difference plus charizard's drought with solarbeam combo is big threat to seismotoad and heatwave kills off avalugg and ferrothorn, earthquake rids u of chandelure
