Well, Tutor, you definitely got some Item problems here.
Well, Gorebyss is fine. Problem is, while you're setting up, someone will definitely attack you, and that, paired with Life Orb, will decrease your longevity. I suggest White Herb or Focus Sash, though I always preferred White Herb. Of course, I do have a replacement for it though.
Ludicolo (M) @ Life Orb
Trait: Swift Swim
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Rain Dance
- Hydro Pump
- Giga Drain
- Ice Beam
Your whole team has been sweeped by this beauty. Offensive Rain Dance Ludicolo is as good in Defense as in Offense, with a great typing giving him a quad resistance to Water-types (Your team is Water-weak, having one Pokemon weak and none resistant, except Gorebyss, who is very frail). Once this guy sets up Rain Dance, the only thing that can stop him is Rain Dish Ludicolo, who is getting popular for being able to counter Offensive Rain Dance Ludicolo. The moves are pretty self-explanatory. Rain Dance starts rain while Hydro Pump is Rain-boosted STAB. Giga Drain is STAB and reliable recovery while Ice Beam is additional coverage and hits Grass-types for super-effective damage.
Golurk is lovely. No suggestions.
Corsola is a pathetic Pokemon, even with full SDef investment, Lickilicky does better than him. And that's who I'm suggesting.
Lickilicky (M) @ Leftovers
Trait: Own Tempo
EVs: 252 HP / 252 SDef / 4 Spd
Careful Nature (+SDef, -SAtk)
- Wish
- Protect
- Heal Bell
- Body Slam
Some people will blame me for copying a Smogon set. I actually use this beast in a defensive core w/ Luxray (It's fantastic). 'Nuff said.
On to Weezing. I prefer this set:
Weezing (M) @ Black Sludge
Trait: Levitate
EVs: 252 HP / 252 Def / 4 SAtk
Bold Nature (+Def, -Atk)
- Will-O-Wisp
- Clear Smog
- Sludge Wave
- Pain Split
It's a nice set, and anyways, Weezing isn't fit for attacking much. Plus, he makes a great Defensive core with Lickilicky!
Lol, Special Pikachu w/ Light Ball is wayyyy better.
Pikachu @ Light Ball
Trait: Lightningrod
EVs: 252 SAtk / 252 Spd / 4 Def
Timid Nature (+Spd, -Atk)
- Substitute
- Thunderbolt
- Hidden Power [Ice]
- Grass Knot
Switch into a Choiced user using an Electric move, use Substitute and start sweeping. xP
For Gurdurr, this wittle baby should have this:
Gurdurr (M) @ Eviolite
Trait: Guts
EVs: 252 HP / 252 Atk / 4 SDef
Adamant Nature (+Atk, -SAtk)
- Bulk Up
- Drain Punch
- Mach Punch
- Ice Punch
Smogon sets are outdated xP. Anywho, Eviolite + Bulk Up gives him phenomenal bulk. Wowzah =D
Well, I hope I helped you!
