I just beat the main story, I'll post my various teammembers, but I'll start with these two. Aron - Low Tier -Availability: After the fifth Gym, accessed in Mistralton Cave with Surf. -Stats: Aron and its evolutions can take any physical attack bar Fighting or Ground and laugh at it. Even Aqua Tail only tickles. Aron and its evolutions have pretty good Attack. Their low Speed can be somewhat rectified with Automatize, however their low Special Defense cannot. -Movepool: Aside from the ton of special moves Aggron can learn and not use effectively, you have Rock Slide, Iron Tail, Bulldoze, Iron Head, Aqua Tail, elemental punches, Take Down and Double-Edge. Automatize and Rock Polish can help with the Speed issue. -Major Battles: Lairon/Aggron can clean Skyla and Team Plasma pretty easy (Colress will whip him though) and help against Drayden's Haxorus, but otherwise isn't all to useful. Marlon is suicide and the Elite Four all have Pokemon or move that can one shot Aggron pretty readily unless you have Sturdy. Oh, and you fight a ton of Fighting- and Water-types later in the game, so have fun with that. -Additional Comments: Good stats, good movepool, but lategame BW2 is just way too cruel on that typing. Sturdy is appreciated but only somewhat fixes the issue. Considering all the Steel-types you could be using (the insanely powerful Magnezone, the indestructible Skarmory, the versatile Lucario or the disgustingly durable Ferrothorn, for example), adding Aggron to your team probably isn't doing you any favors. I really like Aggron and thought it was amazing in RSE, but Black and White 2 is just too brutal to it. Tangela - Mid Tier -Availability: After the sixth Gym, right around Undella Town. -Stats: You have two options here. You can use Eviolite Tangela, who is slightly faster and has ridiculous bulk, or Tangrowth, who has more Attack, a wider movepool and more item options. Tangrowth's only flaw is its pathetic Special Defense (mine was Sassy and it still couldn't take special hits well), since it has enough bulk to pretty much take anything thrown at it before retaliating. It's offensive stats are great. -Movepool: Use a Heart Scale to get Sleep Powder first and foremost. Tangrowth's offensive options include Giga Drain, Power Whip, Energy Ball, Bulldoze, AncientPower, Return and Rock Slide: a lot more expansive than many other Grass-types. It also has Stun Spore, but Sleep Powder is generally more useful. Tangela's movepool is worse. -Major Battles: Tangrowth/Tangela can solo Marlon no problem. Against Drayden and the Elite Four/Champion it stands out for being able to tank hits while you heal your main attacker or debilitate them with Sleep Powder. Giga Drain/Power Whip does a nice chunk to neutral Pokemon as well. With Bulldoze, it can somewhat handle Team Plasma as well. -Additional Comments: Tangela got extremely lucky with its placement in the game. It is found in a route full of fishermen and between Undella Bay and Reversal Mountain, so you got a lot of Water-, Rock- and Ground-types to train on. After a short training session with Lucky Egg, Tangela/Tangrowth is ready to go. Very good Pokemon, only held back by the fact Lilligant is so damn amazing.
