So it took me a while and I've decided to make an ORAS OU team. Sorry I couldn't figure out how to upload photos.
Metagross
Item: Metagrossite
Ability: Clear Body/Tough Claws
Nature: Adamant
EVs: 252 Attack/176 Speed/80 HP
Move 1: Zen Headbutt
Move 2: Meteor Mash
Move 3: Earthquake
Move 4: Rock Polish
I chose Metagross as my mega because I like his big Attack and Defense as well as his ability Tough Claws which increases the power of his attacks. I wanted an Adamant one for more Attack. I maxed Attack and gave it a lot of Speed to help it sweep with Rock Polish and give it HP to let it take a few hits. I taught it Zen Headbutt and Meteor Mash for STAB and Earthquake for coverage. Rock Polish helps it outspeed most of the tier.
Clefable
Item: Leftovers
Ability: Magic Guard
Nature: Calm
EVs: 252 HP/172 Defense/84 Special Defense.
Move 1: Moonblast
Move 2: Calm Mind
Move 3: Stealth Rock
Move 4: Thunder Wave
I chose Clefable because I wanted a Fairy type for coverage and a hazard setter. I also like Clefable's ability Magic Guard so it doesn't take damage from Burns, Poison, etc. I got a Timid one so I could have higher speed. I maxed out HP so it could stay in longer, gave some Defense and Special Defense so it can take some hits. I gave it Leftovers so it could regain HP while it sets up traps and uses Calm Mind. I taught it Moonblast for STAB, Calm Mind so I can build up Moonblast's power, Thunder Wave so I can use paralysis, and Stealth Rock for an entry hazard.
Feraligatr
Item: Life Orb
Ability: Sheer Force
Nature: Adamant
EVs: 220 Attack/252 Speed/36 Special Defense
Move 1: Dragon Dance
Move 2: Waterfall
Move 3: Crunch
Move 4: Ice Punch
I choose Feraligatr because I wanted a Water type for coverage and I liked Feraligatr's Hidden Ability to increase its power. I gave it an Adamant nature to increase its power move and gave it a Life Orb so I can get more power and Sheer Force removes the effect of the orb's recoil. I maxed it's Speed since Feraligatr's speed is not the best, almost max attack for more power, and some Special Defense since it has lower Special Defense that Defense. I breed Dragon Dance onto it so it can increase it's Attack and Speed more, Waterfall for STAB, and Crunch and Ice Punch for coverage.
Goodra
Item: Choice Specs
Ability: Sap Sipper
Nature: Modest
EVs: 212 HP/252 Special Attack/44 Speed
Move 1: Draco Meteor
Move 2: Muddy Water
Move 3: Fire Blast
Move 4: Sludge Bomb
I chose Goodra because I wanted a Dragon type and I wanted a bulky Special Attacker. I wanted Sap Sipper so I can have an immunity to Grass (especially Leech Seed). I gave it a Modest nature increase Special Attack. I gave it Choice Specs to increase Special Attack even more. I gave it almost max HP so it can take hits and gave it max Special Attack, and I gave it some Speed as well. I taught it Draco Meteor for STAB, and Fire Blast, Muddy Water, and Sludge Bomb for type coverage.
Weavile
Item: Shell Bell
Ability: Pressure
Nature: Jolly
EVs: 252 Attack/4 Defense/252 Speed
Move 1: Icicle Crash
Move 2: Ice Shard
Move 3: Low Kick
Move 4: Knock Off
I chose Weavile because I wanted a fast physical attacker. I wanted a Jolly one to increase Speed. I gave it a Shell Bell so it can recover HP right after it hits. I maxed Attack and Speed and gave it a small Defense boost. I breed Icicle Crash and Knock Off for STAB, Low Kick for coverage (such as against Bisharp), and Ice Shard for revenge kills.
Jolteon
Item: Focus Sash
Ability: Volt Absorb
Nature: Timid
EVs: 252 Special Attack/252 Speed/4 Special Defense
Move 1: Thunderbolt
Move 2: Volt Switch
Move 3: Signal Beam
Move 4: Shadow Ball
I choose Jolteon because since Weavile is my fast physical attacker, I wanted a fast special attacker. I also like it's ability so I can absorb Electric attacks and heal at the same time. I gave it a Timid nature and max Speed so it can sweep, and maxed it's Special Attack along with a small Special Defense boost. I gave it a Focus Sash since it's a little Defensely. I taught it Thunderbolt for STAB, Volt Switch in case I need to switch out, and Signal Beam and Shadow Ball for coverage.
I would appreciate any suggestions.
