I will be doing a team for Pokémon Black/White 2 or Blaze Black/Volt White 2.
First up is your Starter.
Emboar @ Expert Belt
Nature: If you’re going all special I recommend getting Quiet/Modest and if you’re going Mixed then I suggest getting Brave/Quiet
Attacks: Flame Thrower/ Fire Punch/Flare Blitz, Earth Quake, Focus Blast/Hammer Arm/Brick Break, and Scald.
I use Fire Punch over Flare Blitz because of the accuracy and I only use Flare Blitz if I’m playing BB/VW2, Earth Quake for S.T.A.B (if playing BB/VW2). Focus Blast for S.T.A.B, Hammer Arm for Accuracy, Brick Break if you don't want the speed drop from Hammer Arm and Scald for coverage.
Ability: Torrent/Shell Armor
Attacks: Surf/Water Fall/Aqua Tail, Revenge/Super Power, Ice Beam/Dig, and Megahorn
Surf, Water Fall & Aqua Tail is for S.T.A.B, Revenge, Super Power, HP Fighting is also for S.T.A.B. if you play BB/VW2, Dig and Megahorn is there for coverage and Ice Beam is just there.
Serperior @ Miracle Seed/Big Root
Attacks: Coil, Aqua Tail, Return, and Leaf Blade. Leaf Storm/Energy Ball/Solar Beam, Giga Drain, Leech Seed/Synthesis, & Dragon Pulse/Spore/Sunny Day.
I see the first set a lot, but I'm not going to change it because if it's not Baroque don't fix it. Leaf Storm is for Contrary, Dragon Pulse is for S.T.A.B if you’re playing BB/VW2, Energy Ball if not, use Solar Beam in conjunction with Synthesis & Sunny Day, use Giga Drain or Leech Seed for damage while healing and spore is there if you want to put a Pokemon to sleep.
Now for the other Pokemon.
Depending on which Starter you choose you can replace one of these Pokemon with it.
