Ok, so I will be rating! And another thing.... Thanks for stealing my answer, Genga =-=.
I am (was, in fact.) a proud user of Lapras. So I will giving you a new set, the one I used with much success:
Lapras (M) @ Leftovers
Trait: Water Absorb
EVs: 252 HP / 120 Def / 136 SAtk
Modest Nature (+SAtk, -Atk)
- Surf
- Ice Beam
- Thunderbolt
- Toxic
Toxic over Heal Bell so the poison Status on Swellow stays. EV Spread makes him a tank.
On to Swellow. You're missing 4 EVs, preferably in Defense. Try Flame Orb instead of Toxic Orb.
I also used Machoke before and all I know is that Gurdurr is a better Bulk Up user than him. And I am suggesting Gurdurr over Machoke.
Gurdurr @ Eviolite
Trait: Guts
EVs: 252 HP / 252 Atk / 4 SDef
Adamant Nature (+Atk, -SAtk)
- Bulk Up
- Drain Punch
- Mach Punch
- Ice Punch
Bulk Up is used for getting more bulk in there, hence the name. Drain Punch is to shrug off most of the damage dealt to you while setting up and is STAB. Mach Punch is STAB and very useful priority. Ice Punch is coverage against Flying types and hits Amoonguss hard, who would normally switch in to absorb all the Fighting moves or to use Clear Smog.
On to Duosion. You may be fond of de Reuniclus family but seriously, Duosion over Musharna?! No way. Plus, Musharna makes a great core with Gurdurr (Credit to Smogon for that). So I am suggesting Musharna over Duosion.
Musharna @ Leftovers
Trait: Synchronize
EVs: 252 Def / 228 HP / 16 SDef / 16 SAtk
Bold Nature (+Def, -Atk)
- Calm Mind
- Moonlight
- Psychic
- Signal Beam
Basic Smogon set with slightly altered EV Spread as he already has enormous HP Stat. 'Nuff said.
On to Lairon. I think that all he's doing is adding weaknesses to your team. Plus, ATM, you have a triple Electric weakness O.o. We'll be replacing him for a Ground type, and a good one. Golurk!
Golurk @ Life Orb
Trait: No Guard
EVs: 252 Atk / 164 Spd / 92 HP
Adamant Nature (+Atk, -SAtk)
- Earthquake
- Shadow Punch
- DynamicPunch
- Stealth Rock
He's one of my favorite Pokemon in NU. No Guard is a great ability, allowing him to abuse DynamicPunch. EVs are weird but they allow him to outspeed some stuff so yeah. Earthquake is STAB and so is Shadow Punch. DynamicPunch always confuses. When you're sure that the opponent will switch, you can set up Stealth Rock.
If I let you keep Gorebyss, you'll have a triple Electric type weakness. No thanks. Replacing him for one Special Attacker that's starting to stand out: Electabuzz.
Electabuzz @ Eviolite
Trait: Vital Spirit
EVs: 252 SAtk / 252 Spd / 4 HP
Modest Nature (+SAtk, -Atk)
- Thunderbolt
- Volt Switch
- Hidden Power [Ice]
- Focus Blast
Easy to figure out the strategy of this little guy. Eviolite gives him more bulk.
Well, that's the end of my rate! Hope I helped you!
