Building process and explanation:
I made this team like 2 weeks ago, because I like volcanion, I tried to build with volcanion many times, but all teams were weak to a meta-thing or they were simply bad, so I decided to ask for a team on thw workshop and snowy did me a team, but I'm very stubborn and I didn't stop until I build a good team, so here is this team.
Obviusly volcanion was the first mon I added. Then I added latios, because volcanion is weak to hazards and rocks and latios is a electric and ground resist. Lando was added for rocks and because of the momentum it generates with u-turn. It was also a zyg check. Then I added koko for a volturn core, it also helps with the speed of the team if lati is dead. In the fifth slot, celesteela was added to stop lele (before it breaks the team). It is also a ground resist (the third ground resist lmao).In the sixth slot, I needed a mega and a grass, and... meganium was added! jk, I add venusaur for checking better things like keldeo. The sets I think are very standard, the only things to remark is eq venu for having a good way to deal with tran, than can be really anoying. I'm using z-wild charge koko (that isn't too good right now) instead of specs or z-special for heatran mostly and to taunt some passive mons, also remarking that this koko set is more for supporting the other mons than for doing a kill each time you switch to it.
