@ PlatinumDude
Most of your sets would be good if I was not doing this challenge. This team would also just be battle my friends and not used online.Also, as i said before, my pokemon are already bred as part of the challenge, so I can't change them.
Absol: I disagree that it is only good if it is a mega. I have another absol that swept two completely different competitive teams without even being iv bred. I also don't like the idea of special moves on an absol, as that stat is horrible.
Mawile: I cant use the leftovers on him as my emolga needs it. Ill drop the doubleteam, and use play rough, but keep it mega.
Ninetales: The reason i picked this set was because it will be unexpected by the people I would fight with it. I also can't get painsplit on it, as i don't have bank to transfer one over. Also, as hp is it's lowest stat, it seems to be a waste, and i would rater have more spatk.
Emolga: This emolga relies on mawile to pass boost to it. Also, once again, can't have tailwind for same reason as painsplit. Maybe use this moveset? wild charge, agility, substitute, and baton pass?
Gallade: This set would be good, but again, i can't get it. I already have a dark type with a priority attack, so knock off seems pointless. I will drop e-quake, power up punch, and x-sissor for rocktomb Close combat, and psycho cut. I think i'll keep poison jab.
Sylveon: I can't get hyper voice, healbell, or wish on this pokemon because of various reasons. I will use psyshock and moonblast.(as close as i can get to hyper voice) Not sure what else to use on it with these.
I actually agree with MoxieInfinite about Absol. Your may have played against incompetent opponents when you used that non-Mega Absol. As I mentioned before, non-Mega Absol's Speed leaves much to be desired, and its frailty doesn't help in that case, making its Mega form outclass the regular form in every way possible.
Drop the Mawilite on Mawile, since Absol will be taking the Mega slot. Give it Sitrus Berry or Lum Berry if you're strapped for items.
While HP is one of Ninetales' lowest stats, it needs the extra general bulk to survive hits.
Speed-passing is better done by Gorebyss or Scolipede, as I already mentioned.
Knock Off isn't a priority move. It simply strips the opponent of its item while inflicting damage.
Pixilate is useless if you don't use a Normal move on Sylveon.
If you want to have access to B2/W2 tutor moves, buy Pokemon Bank on the eShop, get enough Shards to teach the appropriate moves in B2/W2, then transfer those Pokemon over.
