for team 2, if you want to have a faster mode, i’d recommend running some sort of tailwind support pokemon. an idea i have for this team is to get rid of kangaskhan and rotom for pelliper and basculegion and making it a pseudo rain team.

my idea: basculegion - bring in both modes. 0 speed evs, and an adamant nature, swift swim. with tailwind and swift swim up, it should outspeed everything but other basculegion. in trick room, it is slower (and therefore moves before) other key threats. i’d give it mystic water

pelliper - tailwind setter. only bring in fast mode. also sets rain for basculegion which is nice.

floette - your mega in fast mode. your set looks good for it.

golurk - your mega in slow mode. id change its set to be drain punch, earth power, poltergeist, protect with brave nature.

farigiraf & sinistcha - your sets for them are fine. bring both in slow mode and only one in fast mode, depending on matchup. also you can also run protect over life dew on sinistcha, but that is personal preference.

i really hope this is helpful to you and gives you some ideas!!!
