Well my b frontier team is
Milotic lv.50Hydro pump, surf, ice beam, recover
swampert lv. 50Hydro pump, surf, ice beam, earthquake
Metagross lv.50 Meteor mash, sludge bomb, thunderpunch, psychic
As you can see i like hydro pump, ice beam and surf.
NO! That team will NOT work. Everyone there is weak to grass, and guess what? tons of people at Bf have grass!
take away metagross and replace it w/ blaziken/torkoal.take away milotic and put in Sneasel.
then you will have a good team.
My normal team is:Rayquaza lv.100Areial ace, earthquake, surf, dragon claw
groudon lv.71strength,solarbeam, fissure, earthquake
kyogre lv.70surf, hydro pump, ice beam, sheer cold
dragonite lv.60surf, outrage, fire blast, thunder
scizor lv.60fury cutter, slash, swords dance, metal claw
steelix lv.60iron tail, crunch, sand tomb, double-edge (ability rock head)
A good overall team, but if yoiu were facing me my dragonite would demolish.
[Dragonite 100]IcebeamDragon ClawFly Flamethrower[good moveset]
My only suggestion would be to take away scizor and put Rhydon.
And also give the dragonite the moveset above.
Also, fore some strange reason I dont believe that is your real team. YOU DONT HAVE FLY!!!!!!!!!!!!!!!!!!(not saying that it isnt real)
