Strategy behind it:
This is supposed to be used as your lead, and especifically to beat the common leads. Bronzong can't put you to sleep or Explode on you- you can Trick your Band the turn it Stealth Rock so it's essentially useless, and you can also hit it with Shadow Claw for the 3HKO (but Shadow Claw has a high crit rate, so it may turn out into a surprise 2HKO). Shadow Sneak OHKO's Gengar 100% of the time. Will-o-Wisp is your answer to Gyarados, and you're actually faster than BulkyDos (reaching 227 Speed with that spread). You're faster than Tyranitar too, and you can Wisp it, since switching out means getting hit by Pursuit. Late game, besides having a very powerful priority move, you can also Trick your CB into Blissey or anything else that wouldn't really like it.
Risk/Reward:
As with every other Trick user, you can always mispredict and give your item to something that would like it. You're basically walled by Normal-types, too, but not all of them like a Will-o-Wisp, and those who don't mind it won't really like CB. You just need to predict well [lolol but isn't that what Pokémon is about?]
What its niche is in an OU team:
A nice response to many common leads- and it doesn't become useless later, since Banette has three free switch-ins: Fighting attacks, Normal attacks, and Sleep-inducing moves. That gives you some nice opportunities to come in and do your devious work. Insomnia is a pretty good trait that not many others have access to- and in a metagame where you need a sleep absorber, nothing cooler than not having to rely on Sleep Talk.
Besides, it's Banette. It's just so awesome.
