Just thought I'd help out with some UU CBers:
Gligar (M) @ Choice Band
Trait: Hyper Cutter
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Earthquake
- Hidden Power [Flying]
- Rock Slide
- Sludge Bomb
410 Attack STAB EQ is going to hurt. Hyper Cutter is awesome for a CBer, as it's attack cannot be lowered.
Solrock @ Choice Band
Trait: Levitate
EVs: 252 Atk / 120 Def / 136 Spd
Adamant Nature (+Atk, -SAtk)
- Earthquake
- Rock Slide
- Shadow Ball
- Explosion
You could just max speed and attack, but I like my Solrock to be a bit more durable.
Fearow (M) @ Choice Band
Trait: Keen Eye
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)/Jolly Nature (+Spd, - SAtk)
- Drill Peck
- Frustration/Double-Edge
- Hidden Power [Ground]/[Fighting]
- Quick Attack
Very OU-UU pokemon (if you know what I mean). Common starter, nad hits everything hard. Double Edge is risky, but KOs more stuff.
Muk (M) @ Choice Band
Trait: Sticky Hold
EVs: 252 Atk / 116 Def / 140 SDef
Adamant Nature (+Atk, -SAtk)
- Sludge Bomb
- Explosion
- Hidden Power [Ghost]
- Focus Punch
Focus Punch/HP Ghost cover everything, and Explosion OHKOs a lot. Sludge Bomb is awesome for a STAB move, and poison is great.
Ursaring (M) @ Choice Band
Trait: Guts
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Focus Punch
- Return/Body Slam
- Earthquake/Sleep Talk
- Hidden Power [Ghost]
Again, Focus Punch/HP Ghost coverage. Try to get this thing in on a Thunder Wave. Sleep Talk is an option for taking Status and activating Guts.
Kangaskhan (F) @ Choice Band
Trait: Early Bird
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Return
- Earthquake
- Focus Punch
- Shadow Ball
Suprisingly fast, with over 300 Speed, hits hard with STAB Return too.
Nidoking (M) @ Choice Band
Trait: Poison Point
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Megahorn/Rock Slide
- Sludge Bomb
- Earthquake
- Shadow Ball
Double STAB is awesome on Nidoking.
Stantler (M) @ Choice Band
Trait: Intimidate
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Earthquake
- Return
- Shadow Ball
- Thunder Wave
Cool UU Starter, Thunder Wave the first turn, and then switch out. They still won't know you've got CB. Intimidate just makes this thing even cooler.
Golem (M) @ Choice Band
Trait: Sturdy
EVs: 252 Atk / 54 Def / 204 Spd
Adamant Nature (+Atk, -SAtk)
- Earthquake
- Focus Punch
- Rock Slide
- Explosion
350 att, 177 Speed (outspeed non speed skarm) and 309 Def. Just don't let him take a special hit!
Hope this helps.
