help with my team

[Hyunbin]

i figured out that most pokemon in my team are cut out for a little sandstorm strategy
so i picked these six pokemon, but i need help with movesets, ev distribution and maybe some replacements here and there (just not flygon or shuckle lol)


FLYGON (Special Sweeper)
Levitate /Leftovers

- Fire Blast
- Dragon Pulse
-
-

ARMALDO (Physical Sweeper)
Battle Armor /Leftovers

- X-Scissor
- Stone Edge
-
-

TYRANITAR (???)
Sand Stream / Leftovers

-
-
-
-

SHUCKLE (Tank)
Sturdy / Leftovers

- Toxic
- Double Team
- Rest
- Gastro Acid

CLAYDOL (Tank/Screwer Upper)
Levitate / Leftovers

- Rapid Spin
- Cosmic Power
- Stealth Rock
-

METAGROSS (???)
Clear Body / Leftovers

EDIT//
i know that my friend who wants to battle me will probably use palkia, snorlax and rhyperior (95% sure)

Claydol is in my opinion, a bad choice. It has six weaknesses: Bug, Dark, Water, Ice, Grass, and Ghost. A better physical Sweeper other that Armaldo that would still fit your Sandstorm team would be Scizor.
Scizor@ Scope Lens
Steel/Bug
-X-Scissor
-Sword Dance
-Iron Head
-Night Slash

I know you dont want to get rid of Shuckle, I know it has the Defense of a God, but its HP dosent make it worth it.

yeah scizor sounds better
i have one with those moves (besides swords dance)
but its ivs are so crappy so i'm not using it
and i can't get another one unless i trade (which i can't) T_T
