I Will see what I can do...
First off, Zoroark, awesome choice, really plays some mind games and is fun to switch in and out, here's what I would change:
Shadow (Zoroark) (M) @Focus Sash
EVs: 252 Atk \ 252 Spd \ 4 SAtk
Naive Nature (+Spd, -S Def)
- Sucker Punch
- Low Sweep \ Flamethrower \ Focus Blast
This is a perfect lead Zoro in my opinion, it catches people off guard with the illusion, and it stops set ups with Taunt. Sucker Punch is Taunt synergy and STAB, while adding disruption. U-Turn hits pretty hard and lets you ct as a scout. The next slot is all preference, we left Zoro's Satk stat alone to allow for his spec moves to hit hard, but Low Sweep is also viable, all these will hit Ferro or Scizor if you end up in OU, and they also stop from getting walled by a physical wall or steel type if Zoro is stuck hanging solo.
Reinculus looks like it's set up for Toxic stalling, but has nothing to dispose of Steel types. I would switch Psychic for HP Fire or Ground. Personally, I think there are better T-Stallers, and Reinculus makes for a better dual screener, but that's what I would change there.
Carracosta looks good, only thing I would change is Waterfall for Stone Edge or Knock Down, this will add coverage, as well as remove the redundancy of two physical Water attacks. Knock Down gives the added bonus of being able to EQ Flying types and levitaters the following turn (Zapdos, Eelektross namely). Defensive EVs are kind of a waste given this thing is a suicide sweeper, it cuts it's own stats to boost other, no point investing in something you are going to tear down yourself. My EV spread would look more like this: 48 HP (puts it to 301, Seismic Toss and Night Shade will need to hit 4 times for a kill), 220 Atk, 240 Speed (Puts speed to 160, after two SS a nice 320 speed to work with). Adamant Nature.
I don't know what to say about the next two... Emolga isn't a reliable Paraflincher, it doesn't have the defenses to take hits that get through, or the move pool to be reliable. Leave Paraflinch to the pros (Togekiss and Jirachi). Serperior, a nice idea with coil, and it could be fun, but it doesn't have the move pool to support it, I'll give it a shot though:
Serperior (M) @ Leftovers
EVs: 40 HP / 120 Atk / 96 SDef / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Leaf Blade
- Dragon Tail
- Iron Tail / Pursuit / Leech Seed
This thing is kind of cool, Coil is an awesome stat booster, three stat increases at no cost, count me in. Leaf Blade for STAB and crit ratio, main attack, Iron Tail gets a boost from Coil Acc increase, but it doesn't add much coverage that Leaf Blade doesn't, Pusuit can hit ghosts hard, as well as hit switchers with some force, Leech Seed is good recovery in combo with Coil's defensive upgrade. Dragon Tail is to phaze out other pokes trying to set up, as well as hit dragons with some force and get resisting grass types off the field for a minute. EVs are simple, 40 in HP allows for that magical 301 stat, 120 atk leaves us with an nice round 216 to boost (one coil ups to 324), 96 SDef allows for some bulk while coil inflates physical defence. Serp can move quickly, so 252 Speed and a Jolly nature outspeeds most things thrown at it. Remember Dragon tail has a negative priority, so don't expect it to phase quickly.
Mienshao is awesome if you like to switch allot, with regenerator, it is one of the best Life Orb users around.
Blade (Mienshao) (F) @ Life Orb
EVs: 252 Atk / 252 Spd / 4 HP
Jolly Nature (Spd, -SAtk)
- Hi Jump Kick
- Stone Edge / Fake Out
- Taunt / Fake Out
This thing is a quick physical attacker with a neat utility pool. U-turn is like a signature on this thing, it regens 1/3 of it's HP and brings out another Poke, awesome (it also hits those Psychic types hard, an added bonus). Hi Jump Kick, Stab + Orb is awesome power, no explanation needed really. Stone edge is cool, but it gives almost the same coverage as HJK, I prefer Fake Out due to the prio, flinch, and you are constantly switching this thing as a revenge killer. Taunt or Fake out fits this next spot, as I said, this thing is a Grade-A revenge killer, Taunt stops set ups and recovery from happening, and fake out is still awesome utility.
At this point, I feel like there are too many physical attackers, and no good special sweeper, partly my fault as I shifted Zoro to physical/mixed. I would add a decent Special sweeper to this team, maybe a Zapdos or Sheer Force Nidoking. Given you apparent preferences, I would suggest the Nidoking, it can take care of troublesome grass types and sweep entire teams with the right predictions. I'll give you my personal set up for it:
Nidoking (M) @Life Orb/ Expert Belt/ Wise Glasses
Trait: Sheer Force
EVs: 252 SAtk \ 116 Def \ 84 SDef \ 56 Spd
Modest Nature (+SAtk, -Atk)
-Dragon Tail / Fire Blast/ Flamethrower
This is a pretty cool set up, it deals massive damage (1.3x increase from Sheer Force+ 1.3x increase from Life Orb, 1.2x from expert belt, or 1.1x from Wise Glasses). Earth Power gets stab, coverage, and Sheer Force boost, awesome. Ice Beam and T-Bolt give the infamous bolt/beam coverage, as well as getting SF boosts. The last slot is optional, I prefer D-Tail for phazing and disruption, while others might like the complete coverage of a fire attack (Fire Blast give more power for an Acc cut, Flamethrower gives full beam class coverage, both get SF boost). Evs are simple, Nido's speed isn't great, so let it move a little to avoid speed ties, as well as give it a bit of bulk to take incoming attacks.
Play around with all of your Pokemon, see what's comfortable, and keep playing with them. Also, for your Dragon Dancers, try Dragon Claw rather than Outrage, it doesn't lock you in or confuse, it allows you to sweep more effectively, Haxorus is generally in sweep position after a single dance anyway, no point locking him in when he can tear through an entire team. Hope this helped a bit...
