I'ma rate this one.
The first thing I noticed about this team is: four of your six Pokemon hold a Focus Sash. Including Politoed, which makes absolutely no sense. Also, those battle links don't replay the battle. Your EVs don't follow the 'divisible by 4' rule either (e.g. 127 EVs), which I will fix also. A few other flaws here and there, which shall be fixed now.
Politoed
Firstly, when Politoed misses it's Leftovers so much, you replace it with Focus Sash. And you have a bulky EV spread going, rendering the item next to useless. So remove the Focus Sash and give it back it's Leftovers.
Your EV spread requires fixing too. 4 EVs = 1 stat point. So for an effective spread, each number must be divisible by 4, which 127 EVs is not doing. I propose giving it a Physically Defensive spread; though you have invested balanced bulk on HP, Def and SDef, Politoed is better off going 252 HP / 252 Def / 4 SAtk. Doing this implies changing it's Nature to Bold. Outside of that, Politoed looks good.
Manaphy
Give it a Life Orb. 100 Base Special Attack is nothing impressive, so you need the extra power. After Tail Glow and Rain, you've got a monstrous Special Attacker. Psychic isn't of much use to Manaphy, so give it Ice Beam instead. Done.
Omastar
No more Focus Sash. Give it Life Orb or White Herb; either will work well. Give it Hydro Pump over Surf; extra damage assists it well. Other than that, good.
Sharpedo
Consider Life Orb again, though Focus Sash is more viable here.
This looks good other than that.
Slowking
You don't have a Special Wall yet. So we are going to make him one. Use this set:
Slowking @ Leftovers
Trait: Regenerator
EVs: 252 HP / 252 SDef / 4 SAtk
Calm Nature (+SDef, -Atk)
- Scald
- Calm Mind
- Fire Blast
- Slack Off
A basic Special Wall. Scald is STAB, with a nice little chance to burn. Calm Mind is there for the same reason it was on your set; to boost it's SAtk and SDef, both of which it loves dearly. Fire Blast is used as coverage, though Psyshock can be used as STAB is you want. Slack Off is almost a must have for any defensive Bro or King; healing is big help to it's longevity.
Lanturn
Why Water Absorb when almost all of your team resists Water in the first place? Abuse it's gift of Volt Absorb; use Lanturn to take the Electric attacks that cripple your current team. Also, Lanturn is definitely not your ideal sweeper; it's Base Stats scream 'Tank'. Though if you want to use it as a sweeper, give it Specs.
If you want a Special Sweeper, I offer a replacement for Lanturn in Kingdra; with it's neutrality to Electricity and it's Swift Swim ability, it will be a great addition to your team.
Kingdra @ Life Orb
Trait: Swift Swim
EVs: 252 SAtk / 252 Spd / 4 HP
Modest Nature (+SAtk, -Atk)
- Draco Meteor
- Hydro Pump
- Hidden Power Electric
- Dragon Pulse
Very straightforward. Draco Meteor is hard-hitting STAB, removing anything that troubles it from it's way with it's large speed thanks to Swift Swim. Hydro Pump is also STAB, though with lower accuracy, doesn't have the drop of SAtk that Draco Meter does. Hidden Power Electric is more coverage. Dragon Pulse is Dragon type STAB, but allows Kingdra to use a Dragon move without the SAtk drop.
Good luck with your team.
