OU Sunny Day Team
I like weather. There is just something about getting a tan on a beach. To business though!------------------------------------------------------------------------------------------------------------------------

Nature: Adamant
Ability: Thick Fat
EV'S: 252 Spd/ 252 Att/ 6 Hp
Item: Focus Sash
Moves:
-Earthquake
-Icicle Crash
-Ice Shards
-Stealth Rock
Mamoswine sets up stealth rocks. The focus sash allows it to survive long enough to set up stealth rocks. Furthemore, Mamoswine offers dragon and electric type coverage for my team. Ice shards for revenge kills. Icicle crash is a great stab if I could out speed the enemy with a 30% chance to flinch. Thick fat will help it survive neutral fire attacks despite sunny day being active.

Nature: Modest
Ability: Blaze
EV's: 252 Sp.Att/252 Spd/6 HP
Item: Charizardite Y
Moves:
-Dragon Pulse
-Fire Blast
-Solar Beam
-Roost/Protect
Charizard is going to be my special sweeper for this team. On top of that a drought pokemon will be good for this team. Fire Blast will be doing major damage in the sun with Y's special attack stat. Dragon Pulse for coverage against other dragons that will show up. Solar Beam in the sun will be good coverage against rock and water types. Roost in case I need some recovery. If I end up running protect it probably to avoid some nasty things.

Nature: Jolly
Ability: Blaze
EV's: 252 Att/ 252 Spd/ 6 HP
Item: Choice Scarf
Moves:
-Flare Blitz
-Close Combat
-Thunder Punch
-Earthquake
Flare blitz and close combat are both stabs with flare blitz also being upped by sunny day. Thunder punch is for flying pokemon and the dual typed dragon/flying pokemon. Earthquake can help against rock and electric. Choice scarf allows it to go fast and furious.

Nature: Timid
Ability: Drought
EV's: 252 HP/ 136 Spd/ 122 Def
Item: Heat Rock
Moves:
-Will O Wisp
-Solar Beam
-Flamethrower
-Roar
Will O Wisp to stall with all the HP and Def EV's. Flamethrower stab +sun. Drought and heat rock for very good reasons. Solar beam doesn't need to power up and roar in case something goes bad or I got to remove an enemy wall. More cover for water types.

Nature: Bold
Ability: Levitate
EV's: 252 HP/252 Def/ 6 Spd
Item: Leftovers
Moves:
-Stealth Rock
-Sunny Day
-Earth Power
-Rapid Spin
Claydol will be another pokemon to possible reset up with and remove entry hazards using rapid spin. Earth power is there so it is not completely defenseless. Max defense , leftovers and HP to tank so it can actually reset the stuff.

Nature: Jolly
Ability: Chlorophyll
EV's: 252 Att/ 252 Spd/ 6 HP
Item: Life Orb
Moves:
- Knock Off
-Sucker Punch
-Leaf Blade
-Growth
In the sun chlorophyll will allow it to move fast enough with Jolly nature to use Knock Off and Leaf blade. If i get the occasion growth in the sun can increase shiftry's attack by 2 stages. Sucker punch is a good stab priority move for the tree. Knock off for enemy items. Life orb to give shifty that extra bit of damage he could use.
