I have used the LO Special Sweeper set for a long time, in OU and UU, and it gets the job done. No doubting that set. However, the unburden one is interesting. That set usually just either gets outclassed in OU, or it gets unlucky. I don't think it's good enough; no consistency. That being said, In UU, the set has a chance, because there are less defensive mammoths, and Sceptile has a great coverage. I think add a little more speed, maybe so Sceppy will be over 300 or close to, and the set might work. I'll try it out.
