Sup /vp/

I want to get into competitive battling, but I've never battled before. I beat the game and have been breeding cool looking Pokemon and looking up movesets/natures, etc.

Here's what I have (all perfect IV/natures):
Venusaur (Chlorophyll)
Charizard (Solar Power)
Blastoise (Rain Dish)
Ninetales (Drought)
Vaporeon (Water Absorb)
Espeon (Magic Bounce)
Kangaskhan
Dragonite (Multiscale)
Excadrill (Mold Breaker)
Blaziken (Speed Boost)
Jolteon (Volt Absorb)
Sylveon (Pixilate)
Feraligatr
Greninja (Protean)
Garchomp (Rough Skin)
Volcarona
Tyranitar (Sand Stream)
Infernape (Iron Fist)
Cloyster (Skill Link)
Emboar
Azumarill (Huge Power)
Delphox
Talonflame (Gale Wings)
Gengar

If I wanted a sun team, what would be the best choices? Breeding other mons would be fine too.
