Psycho Cut, Night Slash, Leaf Blade...Do any of those moves fall in the "Special" category? No. Now tell me, how on earth can a Pokemon with all physical moves specially sweep. Same as the comment above. Night Slash is not a move that falls under the "special" category. How on earth can it specially sweep?Basically the same as Absol. Oh, and they're not special sweepers.My god, how in the world is Glaceon a special sweeper? Does a Pokemon with a 65 speed stat seem like a special sweeper to you? Sure, it may have a great special attack stat, but the special attack stat alone does not make a Pokemon a sweeper. Speed stat is also a main issue. It almost always has to have a good speed stat.
Special Sweeper - A Pokemon who can deal a good amount of damage through the use of moves under the "special" category. Special Sweepers almost always have a high speed stat (if not, a move that boosts its speed stat). Most good special sweepers would have a move in its moveset that boosts its special attack, such as Calm Mind or Nasty Plot. A special sweeper is hard to wall because of the massive damage that it can inflict, and the high speed that is hard to outrun.
Glaceon, Gallade, Honchkrow, Absol... none of them fall under this category.

My personal favorite special sweeper happens to be Gorebyss. Now, it may have a low speed stat but it does have Swift Swim. When used in the rain, it outspeeds almost everything and inflicts a great deal of damage through a STAB + Rain boosted Surf / Hydropump. Even through a not-very-effective attack, Gorebyss still gets a good deal of damage through. Gorebyss is also coupled with a very nice Defense stat, which enables it to switch into some rampaging physical attacker with ease. Gorebyss really hasn't been seen in the standard competitive battle field because it is of the UU tier. However, I use Gorebyss on my UU rain dance team and it has won me battles in even the Smogon OU ladder. Gorebyss's filler moves of Hidden Power [ELECTRIC] and Icebeam allow it to hit almost every Pokemon for neutral damage.
