Zangoose for low B sounds good. Any decently strong hit and zangoose dies, and while yes it hits like a truck its p damn easy to check since quick attack is weak and as previously mentioned any decelty strong neutral attack will kill it. The reliance on activating toxic orb also hampers it. It's a gr8 wallbreaker, no denying that, but it has some big flaws. Kangaskhan should prolly be low b too, mainly because its just so damn easy to wall. Escavalier, durant, steelix, rhydon-all very dangerous pokes that can switch in almost for free, since kanga's coverage simply isn't strong enough against these mons. It does wonders against heavy offense, thanks to fake out and sucker punch, but the fact is it is very easy to wall and that imo prevents it from being A rank. Tauros tho is solid A imo. That combination of coverage, power, speed and surprising physical bulk is fantastic and makes it a huge threat against common offensive teams. The fact that its very difficult to wear down thanks to the lack of lo recoil also helps. Tauros isn't particularly easy to wall either-the special fire coverage stops steelix, esca and tangrowth ruining it.
