This is pretty much the first team I've made in NU that I consider to be serious, I guess. It seems to be able to counter a decent amount of the metagame given that you don't make piss poor predictions, but please let me know if I've missed any glaring weaknesses that aren't really possible to play around.
Cryogonal @ Life Orb
Ability: Levitate
4 HP / 252 SpA / 252 Spe
Modest Nature
-Freeze-Dry
-Flash Cannon
-HP Ground
-Recover
Cryogonal is actually a really powerful special attacker that I think people only run for its access to spin. While I think it can be run as a decent spinner due to its special bulk, it's criminally underused as a wallbreaker. It destroys common specially bulky threats like Ludicolo and Mantine, is still pretty specially bulky, pretty fast, and has access to recovery. Flash Cannon is really just there as coverage for the occasional Slurpuff or ice types you come across, and HP Ground is really just meant to hit things like Magmortar that will expect to force you out.
Slaking @ Choice Band
Ability: Truant
4 HP / 252 Atk / 252 Spe
Jolly Nature
-Retaliate
-Sucker Punch
-Night Slash
-Earthquake
On the off chance that you have to sack something off like the aforementioned Cryogonal, this beast will be there to make sure it wasn't in vain. Very few things in this tier comfortably take a boosted stab banded Retaliate on the chin, so take advantage of teams that seem frail or lack a decent physical wall. Most of the time you'll just be clicking Retaliate, but on the off chance you're up against a team with a Haunter or Rotom, Night Slash can kill it on the switch. Sucker Punch will let you pop the occasional setup sweeper, and Earthquake is for those pesky Steelixes and Golems that tend to eat up Retaliates.
Arbok @ Black Sludge
Ability: Shed Skin
248 HP / 252 Atk / 8 SpD
Adamant Nature
-Gunk Shot
-Sucker Punch
-Earthquake
-Coil
The classic set, made with longevity in mind. Switching in on something that can't kill this due to its tasty poison typing allows it to set up a coil or two. After two or three coils, it's over. This thing is really difficult to counter for some reason, as there isn't really enough in the tier that can beat a boosted Arbok. Gunk Shot for acc. boosted stab after a coil or two, Sucker Punch for the tasty priority (since Arbok is still damn slow even after boosting), and EQ for the coverage against those Steel types that Gunk Shot can't touch.
Scyther @ Eviolite
Ability: Technician
252 Atk / 4 SpD / 252 Spe
Jolly Nature
-Bug Bite
-Aerial Ace
-Quick Attack
-Roost
Oh Scyther, what are you still doing in NU and LC ubers? Look at this damn thing. The only thing I can see really wrong with it is it has the double rocks weakness, and even with that is has the Roost for the reliable recovery. Technician boosted Bug Bites and Aerial Aces tend to hurt a lot of things while you have access to the Technician boosted Quick Attack for the easy revenge kills. As if it weren't enough that this thing gets good attack and speed, with eviolite you're sitting on nearly 300 in both of your defenses. It's actually sort of surprising how well Scyther takes hits. Don't get cheeky with this one, tho, as it is outsped by several things that carry rock moves, like Archeops.
Sandslash @ Leftovers
Ability: Sand Rush
252 HP / 4 Atk / 252 Def
Impish Nature
-Earthquake
-Stone Edge / Knock Off
-Rapid Spin
-Stealth Rock
Basically what you have here is the common defensive Sandslash set, with a minor tweak. Instead of the newly ubiquitous Knock Off, I threw Stone Edge on it. While it isn't quite as much utility, you would be extremely surprised how cheeky people tend to play around a Sandslash. Having access to the rock type move really comes in handy when your opponent switches in the defensive Articuno or the occasional Rotom-Fan. However, if you really don't want to take any chances, Knock Off is always still an option.
Qwilfish @ Black Sludge
Ability: Intimidate
252 HP / 4 Atk / 252 Def
Impish Nature
-Waterfall
-Thunder Wave
-Spikes
-Taunt
Another pokemon that I think belongs above NU. Hitting a support pokemon with T wave on the switch and then getting the free taunt off is so annoying and I hate myself for doing it. Qwilfish has crippled more threats than I've cared to count. Also, the free atk drop forces switches every so often, allowing Qwilfish to cripple even more things, which allow for more offensive flexibility with Scyther, Arbok, and Cryogonal. Qwilfish is the king of turning the tides and creating offensive momentum for your team, and it deserves to be mentioned here as such.
Please give me any compliments or criticisms below on things I can improve on this team. Also, I welcome any other fun NU teams that people want to show me, this is easily my favorite tier now that Sigilyph is gone.
