Xerneas
Reasoning: It's a very, very scary fairy. Seriously, when boosted it can rip through the entire tier practically unassisted. Sure, it only has one shot, and Ho-oh, Poison and Steel Arceus give it trouble, but it can get through them too with the proper coverage. Also, dragons, the most prevalent type in the tier, bow before their deer overlord, and can easily be set-up upon.
Moves: Geomancy, in conjunction with Power Herb, is a double quiver dance with no drawbacks, making Xerneas nigh unbeatable from the Special Side in one turn. Moonblast is the standard STAB, that with the Fairy Aura boost, wrecks anyhting that isn't specifically designed to tank it. Focus Blast nails the likes of Heatran and Ferrothorn, while Psyshock is nice for hitting Poison Arceus and hitting Ho-oh on it's weaker physical side, and it allows Xerneas to somewhat function as a mixed attacker without actually being mixed, sorta like Mewtwo.
Spread: This would be the standard spread, which outspeeds Deoxys-S and all scarfers slower than or equal to Garchomp after a boost. I may desire more speed evs at a later time, but that bulk is mighty nice for allowing set up.
Ferrothorn
Reasoning: Ferrothorn can take hits from Kyogre, Normal-Arceus and Xerneas, i.e. the three kings of ubers, like a champ, and can even damage Arceus passively thanks to Iron Barbs. Similarly, Zekrom is of little issue to it, and it easily set up hazards and can actually deal out good damage. Most importantly, it can lure out fire and fighting attacks for Ho-Oh to switch into, and tends to attract dragons which serve as set-up bait for Xerneas.
Moves: Gyro Ball is truly what makes Ferrothorn a potent offensive threat, allowing i to nail the likes of Mega Mewtwo Y, Kyurem and Darkrai and pretty much anything of decent speed. Power Whip, similarly, handles Groudon and Kyogre. Spikes is just a hobby Ferrothorn has to pass the time while it Leech Seeds everything dry, but it is nice to gain further residual damage, especially with many threats in ubers lacking leftovers recovery.
Spread: As Ferrothorn is designed primarily to handle Kyogre and Xerneas, I made it specially defensive, fully investing in special bulk. That said, it retains the bulk needed to tank resisted and moderately powerful physical hits. That small bit in attack assures that Gyro Ball will leave a little more of a dent in the scary Mega-Mewtwo Y (I don't like Mega Mewtwo Y).
Kyogre
Reasoning: It's mother turducken choice scarf Kyogre! The very pokemon that has terrified ubers for the past 3 generations. If you didn't know, a rain boosted full health Water Spout is the definition of power. I love this whale. Fire types cower in fear of this Leviathan. It's ability to revenge kill anything that isn't Palkia or Lati@s is truly impressive.
Moves: The standard stuff. Water Spout, at full health, has base 337.5 power in the rain after STAB. Thunder nails opposing Kyogre and other water types, and is a powerful move overall for those who don't resist it, not to mention the handy paralysis chance. Ice Beam makes the dragons and the grass types keep at bay, and Surf is chosen over Hydro Pump because I prefer the reliability.
Spread: The standard fair for the standard scarfer. Max speed with a speed boosting nature to ensure maximum speed.
Mega-Scizor
Reasoning: As said above I needed something to clear away stealth rock for Ho-oh, and additionally, I wanted something that make Xerneas cower in its hoofs even after setting up. It also functions as a great scout and more importantly is unexpected and uncommon. Many people expect the choice band set, which is great, as it allows me to lure in walls which I can then scout, defog, or recover on.
Moves: If Scizor is going to be a defogger, well then it needs Defog. U-turn allows for scouting and deals solid damage, especially to Mewtwo and Darkrai, although it is not wise to stay in on the former. Bullet Punch is in there for the priority, and is especially useful against Xerneas and Kyurem-W, or truly any frail sweeper. Finally, Roost extends Scizor's lifespan, which is especially useful since it can't hold leftovers.
Spread: A rehash from the standard spread of Gen 5, it allows Scizor to take most special hits, and it's natural physical bulk is retained. Of course, a good portion goes in to power up that Bullet Punch.
Team Threats and Review
Threats include but are not limited to...
- Palkia: If it carries Fire Blast, which it almost always does, Ferrothorn and Scizor are of no use. Ho-oh can not handle it at all in rain, stands meager chances in normal weather, but actually will probably win against it in the Sun. Groudon and Kyogre fair poorly as well, but with the sun up groudon can take a hit and paralyze it. However, Xerneas would gladly use Palkia as set up bait.
- Dialga: Once again, Fire Blast means Scizor and Ferrothorn are out of the question. Kyogre does poorly against it as well, but both Groudon and Xerneas fair well against it, assuming it doesn;t carry a physical steel move in the case of the latter. Ho-oh also does well, but doesn't like taking a Thunder.
- Genesect: All members of the team have trouble with it, depending on the variant. If it has Flamethrower/Blaze Kick, Ferrothorn and Scizor are once again ineffective. Xerneas dislikes the physical variant, neither Kyogre nor Ho-oh are found of Thunder, and Groudon won't appreciate an Ice Beam.
- Arceus: Although Groudon, Scizor and Ferrothorn don;t mind tanking Extreme Speed, Normal Arceus is always a threat no matter what you do in Ubers.
To finish off, this is my ubers team, it has a strict no dragons policy, and feel free to rate and comment as you wish.
