The generation is still very new to competitive and thus different kinds of teams and styles of battling need to be tested (as well as the pokemon themselves) so here's my attempt. Forgive me if the EVs aren't well thought-out, they're what I have to work with at this point considering not much has settled yet.
Anyway, I didn't want to go with a weather/offensive team as most people seem to be doing. Instead I went for some kind of ~balance~. Essentially I just stuck on the things I wanted to try out, and I'll leave it up to you to see how well they look.
Kojondo @ Choice Scarf
252 Atk/40 SpAtk/216 Spe
-Hi Jump Kick
-Hidden Power [Ice]
This is a very interesting fella. I'm leading with him because Scarfed U-Turns are deadly and provide good scouting, however I'm undecided on its ability. U-Turn+Regenerate is very tempting, but you can't overlook the iffy consequences of a missed HJK. Anyway, I already know people are going to overlook Kojondo's SpA, sadly. However, HP Ice with this set is enough to OHKO Salamence, and (though I'm not completely sure) Sazando and Ononokusu.
Nettle @ Shed Shell
Ability: Iron Barbs
252 HP/ 8 Atk/168 Def/72 SpD
Got the EVs off Smogon. Seems beastly to me, not so much as a 100% wall but as an annoying mofo. Power Whip and Gyro Ball do respectable damage, and this resists 11 types. My answer to most bulky waters.
Shanderaa @ Choice Scarf
Ability: Shadow Tag
4 HP/252 SpA/252 Spe
-Hidden Power [Ground]
This isn't a defensive team, so I'm relying on this (and Kojondo I guess) to eliminate threats rather than wall them to death. You should know what this does by now. HP is for Heatran.
Zuruzukin @ Leftovers
252 HP/4 Atk/252 SpDef
Another one I really wanted to try out. Opted to set up its Sp. Def, then Bulk Up away. Base 115 defenses make this bulky as hell, and it looks like it should pack quite a punch. Shanderaa can't touch this.
Gyarados @ Leftovers
156 HP/72 Atk/96 Def/184 Spe
Standard BulkyGyara. What can I say, for years I've been able to fit this on most of my teams because it's so reliably good. Gives another check against most Heatran, though I may run Ice Fang over Stone Edge for the dragons.
Dragonite @ Life Orb
Ability: Inner Focus
116 Atk/200 SpA/192 Spe
Late game janitor. With Gyarados being my only other true sweeper, this ensures I don't get worn out by stall teams. Opted for maximum coverage, as I'm not trying to outlast anyone with this anyway, just beat them as quick as possible.
There you have it. Neither a truly offensive nor stall team, yet I tried to compose it to keep up and possibly beat the current trends in the metagame. I know this is far from an amazing team, and I didn't build it to be one. Just trying what I want to, it's up to you to help me out.
Note: I'm using dream world abilities as we are still pretty much in the speculation stages anyway.
