So to start this off, I'm new to competitive Pokemon. I've been playing since I was a kid but never really got into anything like this until B/W came out so reasoning on pokemon choices might not always be the best.

Haven't faced anyone yet
Wanted to get a team set up before I run around getting owned. Really appreciate any comments or help of any sort. Looking forward to possibly playing some of you guys sometime 
Ninetales @ Leftovers
Ability: Drought
EVs: 4 SpD, 252 SpA, 252 Speed
Nature: Modest
- move: Sunny Day
- move: Solarbeam
- move: Fireblast
- move: Will-o-wisp
So I decided to start a Sunny Day team because fire's always been my favorite type. Charizard
So naturally I have to start with Drought.
Venusaur @ Life Orb
Ability: Chlorophyll
EVs: 4 HP, 252 SpA, 252 Speed
Nature: Modest
- move: Growth
- move: Solarbeam
- move: Earthquake
- move: Sludge Bomb
When first deciding on this team I realized water pokemon wouldn't be fun, and hearing about Chlorophyll on Venusaur I wanted to give him a shot. Growth thrown in to make some pretty STAB Solarbeams
Earthquake and STAB Sludge Bomb used to help team have a slightly better overall coverage
Volcarona @ Leftovers
Ability: Flame Body
EVs: 240 HP, 216 Def, 52 Speed
Nature: Bold
- move: Quiver Dance
- move: Fiery Dance
- move: Bug Buzz
- move: Morning Sun
Next choice was Volcarona. Seemed like a very interesting choice, added more coverage with the added Bug type, and chose to go a little bulky and use morning sun to set up with Quiver Dance.
Infernape @ Life Orb
Ability: Blaze
EVs: 4 SpA, 252 Atk, 252 Speed
Nature: Naive
- move: Overheat
- move: Close Combat
- move: U-turn
- move: Stone Edge
Infernape is a Semi-mixed sweeper more focusing on physical though. Close Combat to help with pesky Special walls (the cursed Blisseys and Chanseys) with Stone Edge to help with flying mostly.
Latias @ Leftovers
Ability: Levitate
EVs: 4 Def, 252 HP, 252 Speed
Nature: Timid
- move: Wish
- move: Roar
- move: Dragon Pulse
- move: Reflect
Latias chosen mostly for wish. I thought wish was going to come in handy in trying to keep my ninetales up. Not fun if that goes down. Also decided to bring in reflect for a team seeming to lack in defense, especially things like Infernape. Dragon Pulse for a nice STAB for dragons that may otherwise prove difficult to handle, with all the fire on the team. Roar was chosen to help with game control and spikes.
Forretress @ Leftovers
Ability: Sturdy
EVs: 176 Def, 252 HP, 80 Speed
Nature: Relaxed
- move: Explosion
- move: Spikes
- move: Rapid Spin
- move: Volt Switch
Finally a little bit of Defense. Thought some form of physical wall was needed because the rest of the team can't take too many hits. Loved Forretress for the fact that it can spike and spin and has pretty good defensive stats. Pretty sure everyone here knows the reasoning on the bottom three moves
But for Explosion, didn't know if that or toxic spikes is better, thoughts?
