Suggestions for this team

[Southit]

Hello, I'm new to pokemmo competitive pvp and I want to build a team in ou with pokemon I like. I thought about this team (I'd surely have fun but I'm afraid it would be too weak)

I built these 3 so far:

Musharna 4x31 (hp, def, spdef, spa)

Bold, leftovers, synchronize, 252 def, 240 hp, 16 spdef

Psychic, calm mind, baton pass, moonlight

 

Chandelure 2x31 (spe, spa)

Modest, scarf, flame body, 252 spa, 252 speed, 6 def

Shadow ball, energy ball, trick, flamethrower

 

Pachirisu 3x31 (hp, def, spdef)

Calm, sitrus berry/leftovers, 252 hp, 252 spdef, 6 def

Super fang, discharge, toxic, reflect (or light screen?)

 

Then I'd like to use vaporeon (wish, protect, scald, heal bell), a life orb garchomp (stealth rock, eq, dragon claw, 4th move?) and an infiltrator jumpluff (swords dance, acrobatics, seed bomb, sleep powder/encore) with focus sash or flying gem

 

Should I abandon this idea or would it be ok with some changes? I'd appreciate any advice, thanks!
