This is my 4th team and everything that is posted is by me so expect the EV spread / Items / Moves to suck!

Torkoal @ Leftovers
Ability : White Smoke
Calm (+SDef / -Atk)
252 Hp / 128 SDef (or SAtk) / 132def
-Will-o-wisp
-Stealth Rock
-Rapid Spin
-Heat Wave
Pure wall or Mix depending on what Ev spread you folks suggest
I'd rather not get rid of Torkoal because I like him very much and I think it will help my team.

Blastoise @ Shell Bell / Leftovers
Ability : Torrent
Sassy (+SDef / -Spd)
252 HP / 252 SDef / 6 Def
-Mirror Coat
-Avalanche
-Aqua Ring
-Surf
I really like this blastoise. Mirror coat for obvious reasons / Avalanche will work due to it's speed and nature / Flash Cannon cause I love that move / and Surf is a filler.

Leafeon @ Leftovers
Ability : Leaf Guard
Impish (+Def / -SAtk) / Adament (+Atk / -SAtk)
252 Atk / 252 Def / 6 Speed
-Curse
-Leaf Blade

Hahahaha. I know Leafeon well look at the next one.

Gentle (+SDef / -Def) / Mild (+SAtk / -Def)
252 SAtk / 252 Sdef / 6 Spd

These two pokemon are Wall / Sweeper Mix that's why I chose them Because well I prefer Defence over offence.

I can get rid of Solrock for a Sweeper
