Pokemon Pearl Nuzlocke Rate My Team [In-Game]

So I am currently doing a nuzlocke and I have made a team that I am thinking about bringing to the elite four. I am not sure what to change about the team but I would like suggestions on what to do with it to improve my team. So here is what I have as a general team. (P.S Yes, I am aware that most of the names my suck but that is because this nuzlocke is almost 3 years old.)

Lvl.62 Seeker (Lucario) (M) @ Fist Plate
Ability: Inner Focus
Lonely Nature
- Close Combat
- Swords Dance
- Stone Edge
- Shadow Claw

This is basically my main sweeper and I wanted to take advantage of its Swords Dance so I made it physical. Close Combat is STAB and Shadow Claw and Stone Edge is coverage.

Lvl.62 Sky-Flyer (Staraptor) (F) @ Soothe Bell
Ability: Intimidate
Relaxed Nature
- Fly
- Double Team
- Close Combat
- Return

This is my MVP and best Pokemon in my team. I gave it Return instead of Brave Bird to avoid recoil and Double Team is there for hax. Close Combat is coverage and Fly is my HM.

Lvl.62 Sir.Quakz (Quagsire) (F) @ Quick Claw
Ability: Water Absorb
Brave Nature
- Rain Dance
- Yawn
- Earthquake
- Waterfall

This is my physical tank, I gave it Rain Dance to support Octillery and Yawn for status. Earthquake and Waterfall are there for physical STAB.

Lvl.62 Snowtree (Abomasnow) (M) @ Icicle Plate
Ability: Snow Warning
Timid Nature
- Sheer Cold
- Giga Drain
- Ice Shard
- Blizzard

This is my mixed sweeper. I gave it Giga Drain for a STAB/Recovery Move and Blizzard instead of Ice Beam to abuse its ability. I also gave it Ice Shard for Priority and Sheer Cold is just for lols.

Lvl.62 Octurrent (Octillery) (F) @ Razor Claw
Ability: Suction Cups
Gentle Nature
- Focus Energy
- Charge Beam
- Flamethrower
- Surf

This is most likely my most gimmicky pokemon and it is also there to work as a special sweeper and I am honestly unsure of this pokemon but I think it my be worth a shot and I really wished that it had Sniper but it doesn't. Focus Energy is to increase the critical hit ratio, Surf is STAB, Charge Beam is Coverage/Set-Up and Flamethower is coverage.

Lvl.62 Nickels (Bronzong) @ Mind Plate
Ability: Levitate
Impish Nature
- Toxic
- Trick Room
- Psychic
- Flash Cannon

This is my wall pokemon. I gave it Toxic for stall, Trick Room to abuse the fact that my team is slow and Psychic and Flash Cannon for STAB.

And for replacement options:
Pokemon In PC: Blissey, Zubat, Pachirisu, Meditite, Ponyta, Kricketune, Machoke, Girafarig, Sneasel, Magikarp and Psyduck


So this is what I got and I appreciate suggestions on Movesets, Items, Levels and other things. So thank you for taking the time of your day to help someone improve their Nuzlocke team. :)

I'd say you're fine with this team. Just replace Focus Energy on Octillery, the move is horrible. Put Blizzard/Ice Beam there. You've got most types covered that you'll see in the league, so you'll be fine ;)
