I've got an NU team here. Please give advice and criticism.
Leafeon (M) @ Leftovers
252 HP/252 Def/4 SpD
In the likely event that my opponent will send out a Pokemon to plague us with Stealth Rock first, I will have Leafeon use Roar on it (or Leaf Blade if I think I can OHKO.) She can baton pass her Swords Dance to the other Psysical Attackers.
Marowak (F) @ Thick Club
252 HP/252 Atk/4 Spe (Should I put more into Speed?)
I plan on sending Marowak out directly after Leafeon. From there, Marowak will put out her Stealth Rock. After that she will be withdrawn until she can get the Trick Room boost from Banette.
Dewgong (F) @ Leftovers
252 HP/252 SpD/4 Def
-Ice Beam/Surf (which will be needed more? I have no water Pokemon, so I think Surf..)
Pretty self explanatory. She uses Hail and surf, goes to sleep and snores, wakes up to use Surf again and sleeps, seemed like it would get pretty annoying to the opponent and drain their PP fast. I probably won't use her until I know the opponent has no Fighting/Rock/Electric type to defeat her with.
Typhlosion (F) @ Life Orb
252 SpA/ 242 Spe/4 HP
Sunny Day will not only help Flamethrower and Fire Blast/Solarbeam, but if Typhlosion switches out for Leafeon, it will activate his Chlorophyll. I think Roar is important for Typhlosion because it has Life Orb so it's already taking damage on itself, I won't be able to afford it taking Damage from things it's weak against.
Banette (M) @ Focus Sash
252 Atk /252 HP/ 4 Spe
Banette will use Trick Room. If whatever move the opponent used would have OHKOd him, he won't faint due to Focus Sash. From there, he will use Destiny Bond. If from then the opponent won't use an attack, I'll use Taunt to force them to. In the event that whatever move the opponent used didn't do much damage, Banette will use Taunt, Destiny Bond, and then Shadow sneak until they faint.
Luxray (F) @ Flame Orb
252 Atk /252 Spe/ 4 HP
-Volt Switch (Yes, it's a SpAtk but it's just a fancy way of switching out plus it has STAB and will do enough damage to those weak against electric.)
Self explanatory, right? Luxray can go in at any point in the battle to get rid of multiple types that my other Pokemon are struggling with. She's fast and Guts + Flame Orb give her massive attack (specially with Facade!) I decided against using Wild Charge for the irritating amount of recoil.
Any comments are helpful. I know my teams can be all over the place. All criticism welcome.
