Another uu noob

Alright, I'm posting this from my phone, so it will be slow and tedious with no pictures until later, but I'll try to make explanations for everything...

At a glance:

Arcanine :: Gligar :: Shaymin :: Blastoise :: Mienshao :: Azelf

Arcanine@Life Orb
Nature: jolly
Trait: intimidate
EVs: 252 atk, 252 spe
Flare Blitz
Wild Charge
Extreme Speed
Close Combat

Let us begin with the end, so to speak. I really wanted to use arcanine, and feels he works quite well as a late game cleaner. Not much else to say, went with full coverage offense set. First thing I think when I choose a fire poke is "yikes! Earthquake!" Which leads me to...

Gligar@eviolite
Nature: bold
Trait: immunity
EVs: 252 hp, 252 def
Roost
Earthquake
U-Turn
Stealth Rock

Physical wall, important earthquake immunity, and the also important stealth rock. Love this guy, as he does a couple jobs well. Also functions as a scout for whatever special threat they want to throw at him.

Blastoise@leftovers
Nature: bold
Trait: torrent
EVs: 252 hp, 252 def, 4 spd
Rapid Spin
Scald
Roar
Foresight

Alright, I've got my hazards, let's clean house with everyone's favorite spinning tortoise. A great bulky water, rapid spinner, and phazer. Also another favorite Pokemon, so that helps.

Shaymin@leftovers
Nature: timid
Trait: natural cure
EVs: 252 spa, 252 spe, 4 hp
Substitute
Leech Seed
Seed Flare
Psychic

What team is complete without a grass type? I considered Roserade, and the fight resist would be nice, but I wanted another ground resist more. I also felt that being hazard heavy would work better with leech seed either keeping the team healthy or forcing switches.

Mienshao@choice scarf
Nature: jolly
Trait: reckless
EVs: 252 atk, 252 spe
Hi Jump Kick
Stone Edge
U-Turn
Hidden Power Ice

Every team needs a choice scarfer, really, and Mienshao is by far my favorite, but how he synergizes with my team may be suspect, but hopefully not. Opinions here, very welcome.

Azelf@life orb
Nature: timid
Trait: levitate
EVs: 252 spa, 252 spe
Nasty Plot
Flamethrower
Psy Shock
Thunderbolt

I felt I needed another late game sweeper and a special attacker, and I feel Azelf covers this, along with the rest of my team, particularly Arcanine, quite nicely. He's frail, but the fighting resist can still be nice. Superb coverage. I was considering a Cofagrigus for this spot as a special attacker and spin blocker, but felt trick room was a bad idea with the rest of the team. Maybe a defensive set would be in order, but would that leave me open to special attackers? Or maybe they're already a big problem for this team. I'm new to UU, but would love to make this team operational...

Arcanine shouldn't run Wild Charge, on paper it may seem nice to have a way to super effectively hit bulky Water types, in reality its too weak to make an impact. Shaymin and Blastoise should be your ways to deal with Water types, not the only fire type on your team. I think Wild Charge should be replaced by either Morning Sun or Crunch. Morning Sun is to heal Arcanine, which is useful thanks to the various recoil it has do deal with, and Crunch it useful to hit Ghost types (especially Chandelure who hard walls your set)

To be honest that's the only real advice I can think of, good job with the team!

Alright, I'll probably switch wild charge to crunch... Something occurred to me though, I don't have anything that can take special attacks, like from chandelure. Should I try to add something to handle that, or just try to keep stealth rocks up and revenge with mienshao or arcanine?
