NU Team

I'm not that great at Gen V, so bare with me here. Here's my NU team and all questions, comments, criticsm is welcomed. In fact, it's wanted.

Thoughts?

I can see some flaws with this team.

While Kecleon is certainly an interesting Pokemon to use, its Color change ability has the potential to backfire on you. Golurk can also set up Stealth Rock while posing an offensive presence, unlike Kecleon, though the lack of recovery hurts:
-Stealth Rock
-Earthquake
-Shadow Punch
-Ice Punch
Nature: Adamant
EVs: 80 HP/252 Atk/176 Spe
Item: Leftovers
Ability: Iron Fist

Why use a Calm nature on Ludicolo if it has Swords Dance? If it were to use Swords Dance, it should be Adamant or Jolly. Heck, Swords Dance Ludicolo isn't that viable anymore:
-Scald
-Giga Drain
-Synthesis
-Leech Seed
Nature: Calm
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Rain Dish

Dual screen support is necessary for Trick Room Beheeyem, and this team doesn't have it:
-Psychic/Psyshock
-Thunderbolt
-Signal Beam/Recover
-Hidden Power (Ground)
Nature: Quiet
EVs: 252 HP/252 SAtk/4 SDef
Item: Life Orb
Ability: Analytic

A Quiet nature ruins the point of Combusken's Speed Boost; change the nature to Modest.
