All right, This team needs some MAJOR tweaking. Lets take a Looksie...
First, Blaziken. Lets keep Blaze Kick, but remove DT, FP, and Overheat. Add Swords Dance, Thunder Punch, and Brick Break. Blaze Kick is their for STAB, Plus it has a high critical hit ratio with the chance of burning the foe, Swords Dance is sorta Obvious, Thunder Punch to take care of Water pokemon, and Brick Break for STAB and to break through the enemy's Reflect/Light Screen.
Now lets replace Articuno with Glaile, since you already have a Flying type (coughDragonitecough). Now lets put Ice Beam on your new Glaile, along with Crunch, Spikes, and Explosion. Ice Beam gets STAB, Crunch for those pesky Psychic types, Spikes to hurt foes switching out, And Explosion for when Glaile is in the red and the opponet is at an attvantige. It can be pretty funny to see your foe's face when your Glaile explodes and knocks out his strongest Pokemon.
I'm going to borow Serebii's Groudon move set. Bulk up, Overheat, Earthquake, and Brickbreak. There you go.
Lanturn should keep surf and Thunder bolt, but delete Thunder and Charge. Put Confuse Ray and Thunder Wave. There is a decent Moveset for Lanturn (I found it helpful at least).
Dragonite Should keep Dragon Dance, but for Sanjuunk's sake, Hyper Beam?! Fly?! What's wrong with ya?!! Let's get rid of them, along with wing attack. Now replace Hyper Beam with Dragon Claw. Then put in Body Slam for the cance of Paralizing the foe. Finnally put Arieal Ace as the finnal move. Why? Because it will never miss. EVER.
For the finnal Pokemon, I Suggest Gardevoir with Destiny Bond, Psychic, Calm Mind, and Fire Punch.This moveset will suprise the foe, so it should work.
Well, I hope this team helps you. Adios!
