Well, since I can't think of any other way to help without just giving you a team, here is a team I made in fourth gen that wouldn't really be relevant now but should give you a good idea of how to build a team. Please understand that much of the mention of threats to the team is irrelevant now, and a couple of these pokemon are no longer OU. However, this team did do well back in the day, and I feel like it is a good example of a solid team, no matter what generation you are talking about. (also I made this quite a while ago, so some of it is going to come across as a little immature in ways. I wasn't nearly as smart as I thought I was. I have edited the descriptions as best I could)
Dragonite @ life orb
Nature; Quiet[+ Special Attack, - Speed]
Ability; Inner Focus
EVs; 224 Attack / 252 Special Attack / 32 Speed
Moveset
Superpower
Flamethrower
Dracometeor
Extreme speed
Description: Amazing anti-lead, destroys everything. Superpower to take out special leads, dracometeor for stab move and taking out anything physical, (defense wise), extreme speed for priority over faster, frail leads. Flamethrower was a coverage move for steel types that could wall me after I had already used Superpower once, because of the lowered attack. It worked very well at the time and my opponents seldom knew how to switch in to a mixed Dragonite, until later that is when this spread became a little more commonplace. I don't think that this setup is viable anymore.
Jirachi @ leftovers
Nature; Bold [+ Defense, - Attack]
Ability; Serene Grace
EVs; 252 HP / 216 Defense / 40 Speed
Moveset
Calm mind
Wish
T-bolt
Psychic
Description: Used for wish support and works well with dragonite by covering his weaknesses. Also as a late game bulky calm mind sweeper. Works well with tyranitar and swampert due to sandstorm. ( meaning he doesn't get hurt by sand storm from t-tar.) As far as I know this Jirachi could very well still be viable in today's metagame. Wish support is good on quite a few teams, but I don't know if his new fairy type was a boon or detriment.
Tyranitar @ choice scarf
Nature; Jolly [+ Speed, - Special Attack]
Ability; Sand Stream
EVs; 252 Attack / 252 Speed / 4 HP
Moveset
Superpower
Pursuit
Crunch
Stone Edge
Description: This is basically a blissey/ghost/psychic killer. And he can sweep some other things after his counters have been removed. has great synergy with pert and Jirachi. Choice Scarf Tyranitar will probably be good for quite a while to come. He won't be much of a surprise very often, as I believe that he is still a common presence in OU. He could also run Fireblast or a different special move. Fireblast allows him to destroy Skarmory and Ferrothorn.
Starmie @ life orb
Nature; Timid [+ Speed, - Attack]
Ability; Natural Cure
EVs; 4 HP / 252 Special Attack / 252 Speed
Moveset
Rapid spin
Surf
Ice beam
Thunder bolt
Description: Spinner, to get rid of rocks and toxic spikes, which really hurt my team, and it is a counter to many threats to other pokemon on the team. Like fire and fighting types ( infernape ) which bother me for some reason. I know that Starmie is still a great spinner, at least in Gen V OU. The moves may need to be changed for coverage, as I am not sure what threats it would need to take care of to keep spinning. Starmie could also be used in a number of different ways and I encourage you to look at other viable Starmie sets.
Swampert @ leftovers
Nature; Relaxed [ + Defense, - Speed]
Ability; Torrent
EVs; 252 HP / 252 Defense / 4 Attack
Moveset
Earthquake
Stealth rock
Roar
Avalanche
Description: Used and abused to set up stealth rock and then phaze with roar. After that, hit apposing poke's with EQ and avalanche until pert is gone. This was a solid option to come in and set up rocks later in the game, seeing as I was leading with the above Dragonite. He was bulky enough to switch in on many OU Pokemon at the time, and set up the rocks in there face. Sometimes I would switch Avalanche to Ice Beam so I could hit dragons on the special side, especially any Salamence that switched in and lowered my attack, seeing as this team was used before Salamence got banned fourth gen.
Flygon @ Choice Scarf
Nature:Naughty[+Atk -SpDef]
Ability:Levitate
Evs:252Atk/252Spe/4SpDef
Fire Blast
Outrage
U-Turn
Earthquake
Description: This was used mainly as a revenge killer, because at the time he was not as severely outclassed as he is now. Garchomp would probably be a better option by now, but he was banned when this team was made. I think I would take out Outrage now, seeing as being locked into that with fairy types running around is a bad idea. U-turn helped to maintain momentum, especially if I knew the opponent was going to switch. A U-turn user is almost always a good idea on any team. Scizor may be a better user of this by now though.
Hope that helps!
