I used Shuckle in BW 1 (Toxic/Rollout/Struggle bug/something) and it did amazingly well. Took 3 surfs from Ghetsis' Hydreigon without dying. From an efficiency point of view yeah, it's terrible. But it's defences actually see use.
Also: I have trained a Sunflora in my main play through, was pretty good. Destroys Marlon easily and does reasonably against the rest of the game. Giga Drain/Leech Seed/Petal Dance is all you really need too, there are so many normal/dark types about. I'm genuinely surprised how good Grass attacks are in general in BW and BW2. I'd still only really place is Mid/Low at best though... Sunkern takes a bit of babying until you get the Sun Stone in Nimbassa and it is as slow as a growing mountain.
