...that's right! It's an NU team! *waits for tumbleweed to roll by* Ahem.
I understand than the boundaries between NU and UU have not been defined, but based on some of the analyses (is that right?) I'll use what I think is probably NU or borderline NU.
Butterfree @ Focus Sash
Timid (+Spd, -Atk)
Compoundeyes
EVs: 6 Hp, 252 Sp. Atk, 252 Spd
~ Sleep Powder
~ Stun Spore
~ Bug Buzz
~ Hidden Power [Fire]
Status in NU is really useful, and when it comes to NU statusing, Butterfree is the best of the best (except for maybe Shroomish). Sleep Powder combined with Compoundeyes provides a 97.5% chance of sleep, which is nice for shutting down lead Pokémon. Butterfree is not pretty fast coming off of 70 base speed, but makes good use of it with Focus Sash paving the way, espically when Hail and Sandstorm are almost completely absent in NU. With a Timid Nature and 252 Speed EVs, Butterfree reaches a nice speed total of 262. When sleep clause is in effect, Stun Spore is like a Thunder Wave that Electivire and Jolteon don't like, except they're absent from NU. Bug Buzz gives Butterfree some kind of sweeping potential off an amazing 80 base Sp. Atk ([/sarcasm]) and scares away leading Mightyena. Hidden Power [Fire] hits other Bugs, Steels, Ice types and Grassers (like Shroomish!), but is mainly there because you hit Mawile, Delibird and all other bug types, as well as those grass/poison types. 252 Sp. Atk EVs let Butterfree hit "hard" off of it's aforementioned 80 Base Sp. Atk, which is pretty good by NU standards, I guess.
Corsola @ Leftovers
Bold (+Def, - Atk)
Natural Cure
EVs: 212 Hp, 12 Def, 252 Sp. Atk, 32 Sp. Def
~ Recover/Rest
~ Surf
~ Calm Mind
~ Mirror Coat
Corsola, yes, that Corsola is actually somewhat usable. Corsola's defenses are actually kind of usable, and while 55 base HP is but, but it's not horrible, no screw that, it is. 212 Hp EVs allow for maximum Leftovers recovery at 304 HP, which is worse than 314. This EV spread allows for that one extra stat point to be used that's usually wasted. Bold Nature lets Furret and Ariados watch in astonishment as their attacks to nothing at all but simply bounce back at them! While Corsola is not good at mixed walling, it's a pretty good Mirror Coat user, which can give some surprises to unsuspecting Pokémon. Calm Mind helps Corsola bulk up (get it? Calm Mind, Bulk Up, *shot*) to stand up to those atrociously powerful attacks coming from those fearsome NU contenders as well a beef up Surf. Recover gives Corsola some staying power after reflecting those terribly powerful special attacks, while Surf is Corsola's absolute best STAB move on the special side of the spectrum. Natural Cure is probably the best ability for a wall, as status conditions mean naught. I don't like the x/y kind of thing on analyses, but Rest is a great move to use with Natural Cure, but it's too situational for my taste (unless someone can please prove me otherwise). 12 Def EVs and 32 Sp. Def EVs improve Corsola's Shuckle-like defenses ([/more sarcasm]). And yes, I did just rant for a Jumpman-sized paragraph on how to use Corsola. Sue me.
Magcargo @ Leftovers
Bold (+ Def, - Atk)
Flame Body
EVs: 252 Hp, 252 Def, 6 Sp. Atk
~ Reflect
~ Recover
~ Overheat
~ Stealth Rock
Magcargo, Mekkah's (?) favorite Pokémon. Sporting a wonderful 120 Base def and a craptastic 50 Base Hp (which, for the record, is worse than Corsola's) Magcargo can wall in NU...possibly. Reflect boosts his already impressive defense to unknown heights, while Recover gives him a chance at staying alive while that terrible Luvdisc threatens to OHKO with STAB Rain Danced Hydro Pump. Reflect is an option that's nice for team support (which an NU team really needs) and with the absence of Brick Break in the favor of Close Combat and Focus Punch (shudder) you can actually expect it to stay up for five turns. As far as attacking goes, Overheat is probably Magcargo's best option--a 140 base power attack (210 after STAB) coming off of 80 Base Sp. Attack (or in this case, 197 Sp. Atk) is not bad--no, screw that, it is. But it is usable in NU, or at least for Magcargo. It's not like Magcargo is going to stay in on anything, so Overheat hits the spot. For more support options, Stealth Rock is an absolute terror in NU (take that you blatantly threatening Beedrill and Dustox!), and let's not forget the absolute terror that is Delibird. Max HP is not only wonderful, but allows for a maximum Leftovers recovery. Bold Nature helps shrug off more physical attacks, and Flame Body encourages physical attackers not to attack for the risk of a burn. Max Defense, as usual, gives Magcargo that much-needed support to take physical hits, while those 4 Sp. Atk EVs give Overheat that extra umph it needs. Oh my god, this is starting to turn out to be a defensive NU team, and I just made another Jumpman-sized paragraph on how to use Magcargo, of all things.
Vileplume @ Leftovers
Calm (+ Sp. Def, - Atk)
Chlorophyll
EVs: 52 Hp, 104 Sp. Atk, 102 Sp. Def, 252 Spd
~ Substitute
~ Leech Seed
~ Sludge Bomb
~ Energy Ball
Hey, it's Vileplume! Sporting a nice 75 Base HP, a high 100 Base Sp. Atk and a good 90 Base Sp. Def, one wonders how she got to NU in the first place. Vileplume causes terror and destruction wherever she goes--and no, it isn't with that horrible stench coming from the flower on her head. SubSeeding, a strategy combining both Substitute and Leech Seed has become a very popular strategy for most grass types. With only 52 Hp EVs, it reaches the magic number--304 Hp. This number allows for two things to happen: it allows for maximum Leftovers recovery and an Hp that is divisible by four. While one may argue it's better to have an Hp divisible by 4+1, Leftovers say otherwise. 104 Sp. Atk EVs put the hurt on Waters, Rocks, Grounds and Grassers who dare switch in with Energy Ball and Sludge Bomb. 102 Sp. Def EVs are there for support because Vileplume will be taking those ugly Ice Beams to the face from Whiscash and Glalie. Coupled with a Calm Nature, a Max Sp. Atk Glalie Ice Beam will deal a nasty223 - 263 or 73.36%-86.51%, as opposed to the possible 89.80%-105.59%. Either way, it's still probably a 2KO, but if Vileplume had no support on the special side, it would probably faint. If it had Max HP and Max Sp. Def, it would still be a 2KO (59.89% - 70.62%). From a Whiscash, Ice Beam deals 52.30% - 61.51%, which while it is still a 2KO, it not nearly a severe when factoring in Leech Seed and Leftovers recovery, making it a 3KO (or possibly a 4KO if a Substitute is up). Chylorophyll is pretty useless, but it might benefit from random sunlight.
Delibird @ Choice Band
Adamant (+ Atk, - Sp. Atk)
Hustle
EVs: 252 Atk, 6 Def, 252 Spd
~ Aerial Ace
~ Rapid Spin
~ Brick Break
~ Ice Shard
Oh no didn't...oh yes I did. Probably the fourth worst Pokémon behind Ditto, Unoun and Luvdisc, Delibird appears wearing a Choice Band. With an Adamant Nature and 252 Atk EVs, Delibird reaches 343.5 Attack, very impressive for an NU Pokémon. Hustle is an ability that gives a 1.5 boost to all physical attacks at the cost of 20% accuracy, which is a very bad thing for a frail Pokémon like Delibird. However, Aerial Ace is Delibird's ace in the hole (get it?) that never misses, so it gains a boost from STAB, Choice Band, Hustle and possibly a 2x/4x weakness on the foe. This means that you have a 135 Base Power attack coming off of 343.5 attack and 249 Speed--very scary, even for Delibird. Although it is the absolute worst one out there, Rapid Spin is a very useful move, even though Delibird is stripped of ~49.9% of it's HP each time it switches in due to them. 0 Hp EVs let Delibird switch into Stealth Rocks twice before dieing, and with Wish support from Chimeco, it may very well actually get something done. While Focus Punch is usually better than Brick Break, think about it, what kind of idiot would switch to a counter on Delibird? Caterpie's Tackle can OHKO it (I admit that was hyperbole), so the Pokémon that's already in can just attack and Delibird dies. Even if they do switch, Brick Break on Mawile and Mightyena is still a 2KO, which is just like Focus Punch's OHKO. Delibird should never ever stay in on Magcargo anyway, so that isn't even an option. Ice Shard is a nice priority move that
Chimeco @ Leftovers
Modest (+ Sp. Atk, - Atk)
Levitate
EVs: 196 Hp, 116 Def, 136 Sp. Atk, 60 Spd
~ Psychic
~ Wish
~ Heal Bell
~ Yawn
Chimeco is probably the most forgotten and overlooked Pokémon on the team 'cause everyone else is ranting about how the other five members suck. Psychic is there for reliable STAB, and 95 Base Sp. Atk is wonderful for NU. Chimeco is another Pokémon on the team capable of using Wish to aid a stricken teammate, as well as heal itself. Status conditions are thrown left and right in every tier, and NU is no exception, so Heal Bell is always welcome on a team. Yawn is a nice attack to force some switches or put something to sleep, and works well with Stealth Rocks up. 196 HP EVs allow for maximum Leftovers recovery (20 Hp) and allow me to dump 56 EVs into Sp. Atk, which adds a nice 14 stat points. 116 Def EVs help Chimeco survive some physical attacks off of it's no-so-impressive Defense stat. 136 Sp. Atk EVs, Modest Nature and a 95 Base Sp. Atk mean that Chimeco can deal a lot more damage than most people think it can. 60 Speed EVs let it outspeed some threats who are sitting around the 50 Base speed mark. By using Levitate, all those ugly ground attacks aimed at Magcargo are nulified. Like Fire Attacks, Ground Attacks can be seen coming from a mile away most of the time. Delibird and Butterfree also are immune to ground, but they take damage from Stealth Rocks, whereas Chimeco doesn't take all that much.
Now, you're probably sitting there going, "Who the hell would sit there for an hour or two and type up a huge analysis on how to use a crappish team, espically in NU?"
And Oh My God, I made a defensive NU team. =P
Oh, and I spelt "unfortunately" wrong in the title. Oops. x3
