I would actually suggest a different Azelf than this one. I'll still keep the same format, which is Lead Azelf, but with slightly different moves.
Azelf @ Focus Sash
EVs: 252 Spd / 200 SAtk / 56 HP
- Stealth Rock
- Fire Blast
- Ice Punch
While yours is a great Azelf in UU, this one works even better in OU. Fire Blast can annihilate leads such as Skarmory, Ferrothorn, and Forretress, while Ice Beam takes care of Landorus and the not as popular Gliscor.
The last moveslot can be a free move of choice , while taunt being the best, the rest are fine too. Of course, if you use Explosion you will need a different nature. Psychic can hit the not as common Focus Sash Terrakion lead.
While Swampert is actually a good Pokemon to use in OU, I would suggest a Specially Defensive Swampert. This is mostly becuase you already have a Gliscor, which is your physical wall, so another one seems almost pointless. Run a EV spread with something along the lines of: 252 HP / 252 SpD / 4 Spe
This will make Swampert a great tankish Pokemon. Also I like how you're running dual Rock setter, very nice and not many of that nowadays.
However, and I know this is a much less creative Pokemon, but have you tried Blissey? It can take a multitude of special hits and forms a great core with Gliscor.
Blissey (F) @ Leftovers
Trait: Natural Cure
EVs: 252 Def / 252 HP / 4 SDef
- Thunder Wave
- Seismic Toss
A great special wall and can also spread paralysis, Blissey can form a deadly core with Gliscor. Trust me, it's not something you want to go up against in a battle. Also, Blissey can also learn Stealth Rock.
Ok, not really seeing what you're doing here. Also, you only have 3 moves :P
Your EV spread suggests an offensive Gliscor, which I don't recommend becuase you already have 3 extremely hard hitters, and this is a more of your defensive core, because unless you're trying to run Hyper Offensive which I don't think you are, a Defensive core is pretty important, well at least to me.
I would try and run a Gliscor that's more like this:
Gliscor (F) @ Toxic Orb
Trait: Poison Heal
EVs: 184 Def / 252 HP / 72 Spd
This is a pretty standard Gliscor, yes it's not fun but I think it will fit into your team very well.
However, if you are trying to run an offensive Gliscor, try this set!
Gliscor (F) @ Flying Gem
Trait: Poison Heal
EVs: 252 Spd / 252 Atk / 4 HP
- Swords Dance
This is a pretty dangerous double set up Gliscor. If you let him set up, well, be prepared to get hit hard.
I am totally going to copy Jar Jar and say run a scarf. Your team is lacking a scarf and Infernape is a great scarfer.
Infernape (M) @ Choice Scarf
EVs: 252 Atk / 252 Spd / 4 SAtk
Naive Nature (+Spd -Def)
- Close Combat
- Stone Edge/Hidden Power [Ice]
Only thing is kind of changed was HP Ice, mainly to hit stuff like Landorus, but it's not like Overheat won't hit them hard. Not really an important move to have, but I'm just putting it out there.
Kudos to you JarJar :D
If you want to keep the Latios with Life Orb, I would say use Hidden Power [Fire] somewhere on there. Scizor can completely demolish you right now, and Ferrothron walls you a lot. Solution? A fire move. I would replace Thunderbolt, but that's me. However, I think a tri Choice core would be nice for this team, which is why I'm saying use a Choice Specs Latios.
Latios (M) @ Choice Specs
EVs: 252 Spd / 252 SAtk / 4 HP
- Draco Meteor
- Hidden Power [Fire]
A lot of people will usually see a team like this and think Scarf Latios, which is why a Specs Latois can hit their Pokemon oh so hard. This guy can really take out some of this teams threats, like Terrakion. Terrakion? Get hit by a Specs Draco meteor :D
So those were my suggestions, I hope you liked them and remember, they're only suggestions, not definite changes. If you don't like them. don't change them.
And as always, good luck and have fun with your team!
