All right, so I just started the Ubers metagame and I am doing okay. I made up (attempted it you prefer =P) to make my 1st Ubers team. I made it to the offensive viewpoint and it is working out okay so far. I have about 3-3 so far, but I wish for more wins instead of losses.
Team Overview:

Team more In-Depth:
Darkrai @ Focus Sash
Timid 4 HP 252 SpA 252 Spe
~ Dark Void
~ Nasty Plot
~ Dark Pulse
~ Focus Blast
Use: I use a Darkrai Lead to start off. I was originally going to try out a Latios, but when I saw this set in the platinum darkrai discussion, I liked it. It actually has been doing okay in the beginning of the game. Dark Void usually is his first attack, unless I am going up against a taunter, then it is either Dark Pulse or Focus Blast. Nasty Plot really helps to boost the danger this guy poses.
Mew @ Choice Scarf
Adamant Nature 148 HP 252 Atk 108 Spe
~ Superpower/Me First
~ Sucker Punch
~ Thunder Punch
~ Ice Punch
Use: I made up this set while looking at Mew and its endless possibilities. I made this set also, and it has been working out okay. Mew definately doesn't pack enough power to kill, but still pretty awesome. The EVs are a bit weird, but my explanation for them is this: 252 atk and Adamant are a must, 108 speed makes me tie with max speed mewtwo, and 148 HP makes Mew a bit bulky. As for the moves, Ice Punch hits those nasty dragons and groudons running around, Thunder Punch does the same for Kyogre/Palkia, Sucker Punch is a nice priority to use on the psychics in the environment, and Superpower is really just filler. I am also wondering on Me First since it can be pretty strong. I really don't know how it functions under a choice item though, so I haven't really tested it yet. Still, it is a possibility!
Kyogre @ Choice Specs
Modest 232 HP 252 SpA 24 Spe
~ Surf
~ Water Spout
~ Thunder
~ Ice Beam
Use: Specs Kyogre is a very powerful being. Setting up rain as he comes in helps out Palkia and makes his powerful Water Spout and Surf very strong. Water Spout is for when I am still healthy, and Surf is for when I am lower in health. Thunder hits other Kyogres and Palkia that might trouble me, and Ice Beam is for dragons! I find Kyogre hitting many teams hard and I like him for that!
Palkia @ Lustrous Orb
Hasty 6 Atk 252 SpA 252 Spe
~ Surf
~ Thunder
~ Spacial Rend
~ Aqua Tail
Use: Palkia and Kyogre are just best of friends! I just love rain, and I'm sure Palkia loves it to. Lustrous Orb helps all of its STAB attacks, while rain benefits 3/4 of the attacks as well. Aqua Tail is on there just in case I come face to face with something that boosts its SpD or Blissey, as Surf just won't do its job! Spacial Rend is a monster attack, and it tears through any dragons that stand in my path. Palkia definately helps out with this team.
Scizor @ Choice Band
Adamant 6 HP 252 Atk 252 Spe
~ Bullet Punch
~ Pursuit
~ U-Turn
~ Superpower
Use: CB Scizor is very powerful. I am thinking about LO, but for now its CB. Pursuit is a must in his moveset, as is Bullet Punch. U-Turn is mainly for scouting, and Superpower is just filler. Not much to talk about here, but he is a must on this team! I am definately very strongly considering LO here.
Deoxys-A @ Life Orb
Hasty 252 SpA 252 Spe 6 Atk
~ Ice Beam
~ Thunder
~ Superpower
~ Shadow Ball
Use: My late game janitor. I usually try to use him very last, but sometimes I catch myself not doing that. LO Mix Deoxys attacks on both attacking stats which is needed for late game. If rain is still going, then Thunder can be very poweful, Ice Beam is for any dragon in my way, Shadow Ball is for the Psychic pokemon that think they can battle, and Superpower is for Blissey and such. Deoxys-A has really been doing a good job of late game sweeping, and I like it for that!
So, that is my first attempt at an Ubers team, so rate away! I am very unexperienced in this field so make suggestions, comment, etc. I will be happy to hear about it!
