battlesubway double's RMT

getting bored of wifi battling so I started messing around in battle subway, I'm terrible at double battle's as I have singles drilled into my head but my friend and I got a streak of 173 in 4th gen with my garchomp and latios and his zapdos and bronzong which was pretty sweet :P anyway heres my team so far ive only started ev training ninetales :L

Ninetales@air baloon/leftovers( I haven't decided who'll be coming in first alongside it yet)
timid 252/4/252
sunny day
solar beam(energy ball?)
fireblast(overheat/flamethrower? hax will lose me games)
protect/nasty plot(hidden power is dragon unfortunately)
what I do know about double battling is its better to hit hard fast so i reluctantly went with a faster set sunny day is for the likes of hippowdon/politoed/tyranitar/abomasnow who will be slower

Darmanitan @ scarf
adamant 4/252/252
flare blitz
u-turn(I'm thinking this is a bad idea)
superpower
rock slide
almost everything is at least 2HKO'd by flareblitz so why not? was thinking of replacing u-turn with EQ I know it has redundant coverage alongside superpower but it's just another option that's also my reason for air balloon on ninetales I'm not sure if I should send darmanitan out first

Victreebel@focus sash (cant get venasaur)
hasty/naive 8/252/248
growth
weather ball
leaf storm(let's face it its not going to last long so it needs to kill)
leaf blade
I'll try and get hp fighting or ground if I can but I can't rng so its too hard

as for the last spot I'm not sure if I should select someone who can sponge attacks if I need to switch or just another sweeper my ideas were:
gastrodon,water,rain,special counter
moxie salamence,ddance,fireblast
banded terrakion for when I need something to die vs sandstorm gets a 50% bonus and easily deals with the likes of tyranitar
multiscale dragonite w/fire punch

so yeah that's my team any idea's let me know, hoping to get to at least get to 50ish
