So here is my latest OU team, and it is by far my most successful team as of yet. It has only lost twice because of opposing Metagross, while winning 20 or 25 battles. This is for Wi-Fi, and and rates would be much appreciated.
Swampert
Relaxed @ Leftovers
252 HP/252 Def/4 SpA
-Stealth Rock
-Earthquake
-Ice Beam
-Roar
Swampert has always been one of the most consistent leads for me, getting Stealth Rock up most of the time. I went with Roar just so I didnt have to deal with the annoying Baton Passers. He is also my secondary answer to Heatran. Main switch into Electivire, Jolteon, Metagross..etc. Swampert also helps deal with Gliscor, the main Lucario counter in the metagame.
Latias
Timid @ Leftovers
4 HP/252 SpA/252 Spe
-Calm Mind
-Dragon Pulse
-Surf
-Recover
Latias is the main special attacker on my team, while also serving as the answer to the ever annoying Infernape. He is also my secondary Calm Mind Sweeper, with nearly unresisted coverage with Dragon Pulse and Surf. Any opinions on whether or not I should use Thunderbolt over Recover for Empoleon?
Porygon2
Bold @ Leftovers
252 HP/216 Def/40 SpA
-Ice Beam
-Thunderbolt
-Thunder Wave
-Recover
Porygon2 is the glue to my team, helping deal with many of the main threats in OU. Destroys Salamence, Gyarados, Heatran, and Jolteon with trace, threatening to either KO or cripple with Thunder Wave. Recover is an obvious choice.
Jirachi
Jolly @ Choice Scarf
4 HP/252 Atk/252 Spe
-Iron Head
-Fire Punch
-Thunderpunch
-Ice Punch
Scarf Jirachi helps with checking many threats in the OU metagame. He is my only real answer to the ever present Scizor, and my main switch in to lucario. Also helps as my secondary option for Gyarados, and probably the only answer to Tyranitar and Mamoswine on the team. Also helps with Zapdos, a common switch in to Lucario.
Salamence
Naive @ Life Orb
24 Atk/232 SpA/252 Spe
-Draco Meteor
-Flamethrower
-Brick Break
-Roost
Mix Mence is here to basically rip holes in the opponents team, which will then be crushed by Lucario. Not all that much to say about Salamence. Helpful for enemy Skarmory and Bronzong, as well as Metagross because it is one of the few members on my team with a fire move. Greatly helps prepare for the imminent Lucario sweep.
Edit: Changed to Naive nature with new ev spread.
Lucario
Adament @ Life Orb
252 Atk/4 Def/252 Spe
-Swords Dance
-Close Combat
-Extremespeed
-Crunch
Lucario, the star of the show. After counters such as Gliscor, Zapdos, and Weezing are out of the way, I can proceed to SD and sweep. Close Combat and Extremespeed are self explanatory. I decided to go with Adament and Crunch for the added power, and the ability to deal with Rotom-A and Dusknoir. I do not have to worry about Gliscor, as Swampert already deals with it, so no ice punch.
The only things that have really given me trouble so far are Metagross and Bronzong. Other than that though, nothing had really given me any trouble.
So there is my team, please rate/comment to improve my team, and just as a reminder, this team is for Wi-Fi.
Thanks, Dukefan5
