Rate my team?

I'm really new at this and I take criticism well. :) Obviously I got these set ideas offline, but I'm not experienced enough to make my own, and I'm just making sure my team is balanced. Thanks!

And last.. I am decided between these two Pokemon:

Garchomp @ Life Orb
- Earthquake
- Dragon Claw
- Swords Dance
- Stone Edge
Trait: Sand Veil
EVs and Nature:
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature

OR

Swampert @ Leftovers
- Earthquake
- Stealth Rock
- Ice Beam
- Surf
Item Attached: Leftovers
Ability: Torrent
EVs and Nature:
EVs: 252 HP / 196 Def / 60 SAtk
Relaxed Nature

Add Swampert and lead with him since Garchomp is banned from standard play anyway. Also 252 HP / 252 Def / 4 Attack is his preferred EV spread.

Also Thunderbolt on Starmie otherwise Gyarados decimates you.

Weavile and Togekiss aren't doing anything for this team. Weavile is excessively metagame weak and can't really lead unless it does its anti-lead set which is pretty predictable, and Togekiss' only two options to pass Nasty Plots to are Magnezone and Yanmega, both of whom are choiced and therefore will be hard pressed to sweep. I'd switch up one of these sets, maybe just give Yanmega a Life Orb and do Speed Boost instead of Tinted Lens, but Togekiss and Yanmega do share the same weaknesses so idk. =/

Thanks yeah, I realized Garchomp is Uber after I posted this.
Okay so I'm definitely dumping Weavile and possibly togekiss..

Wait, togekiss can also pass to Starmie I thought? And somewhat boost swampert?

Don't double post please, just edit your previous one next time.

And Starmie and Swampert can benefit from NP passes but not as much as a dedicated special sweeper would =(

Sorry :embarrass

Yeah I see what you mean. Thanks!
