My first 6th Gen Team.

[iRyahn]

I am not new to the competitive scene and have played on Smogon's servers for a long time. But never before have I actually played competitively on anything but a simulator. So for the first time I have to EV train my Pokemon, and search for perfect IVs. Because of that I thought I should focus on one major team right now, and on perfecting it. So that I don't have to waste to much time EV training and breeding. Here is my current team layout that I am working towards. Feel free to critize or try to improve.

Greninja (Life Orb) 4HP/252Speed/252Sp.Atk
Ability: Protean
Nature: Timid
Moveset: Surf, Ice Beam, Dark Pulse, Extrasensory

Spoiler:

A very simple set. The point is to sweep anything and everything, and with Protean all 4 moves become stabs. Life Orb only puts more salt in the wounds of any foe.

MegaAlakazam (Alakazamite) 4HP/252Speed/252Sp.Atk
Ability: Trace
Nature: Timid
Moveset: Dazzling Gleam, Psychic, Energy Ball, Shadow Ball

Spoiler:

On wifi a lot of fast Pokemon such as Blaziken and MegaGengar have been annoying me to hell and back. Half of the time they sweep me or I survive just by a handstring. So I have decided to get my own annoying fast Pokemon. With 150 estimated base speed, and a Timid nature, not much is going to outspeed this bad boy. His stab psychic kills two of my biggest threats, and for that reason he is on my team as my Mega. Trace can also be very helpful, for example stealing Speed Boost from Blaziken is hilarious.

Shuckle (Leftovers) 4HP/252Def/252Sp.Def
Ability: Sturdy
Nature: Careful
Moveset: Stealth Rock, Sticky Web, Encore, Toxic

Spoiler:

I know he is set up bait, but I really need a mon that can learn Sticky Web+Stealth Rock and there aren't many due to current knowledge. I don't like Smeargle as an option, so I went with Shuckle. The plan here is to get Sticky Web and Stealth Rock up, and then die. Not much else to do.

Donphan (Leftovers) 252HP/4Atk/252Def
Ability: Sturdy
Nature: Impish
Moveset: Ice Shard, Rapid Spin, Earthquake, Roar

Spoiler:

He is here to Rapid Spin away any hazards, as my team can be hindered by any and all hazards quite a lot. I was considering Hitmontop (Intimidate is always nice, especially after it's buff in X/Y) but I chose Donphan. Mainly because Fighting types are much less diserable to me in Gen 6 after Fairy types being introduced. And Grounds are only getting better with Poison and Steel being more common. Quite the standard set, except for Roar, which I feel is a must in certain situations.

Scizor (Choice Band) 248HP/252Atk/8Sp.Def
Ability: Technician
Nature: Adamant
Moveset: U-Turn, Bullet Punch, Pursuit, Superpower

Spoiler:

I figured I needed a strong physical-mon with priority. The first thing I thought of was Scizor. He scares out a lot of Alakazam's threats (glass canon scarfers) and adds a lot of team synergy.

Chandelure (Choice Specs) 4HP/252Sp.Atk/252Speed
Ability: Shadow Tag
Nature: Modest
Moveset: Flamethrower, Shadow Ball, Energy Ball, Will-O-Wisp

Spoiler:

Because of Scizor's glaring weakness to Fire I thought I needed a Flash Fire-mon and found Chandelure. But when I realized I could have Shadow Tag, it was too good to pass up. This set focuses on trapping enemies and killing them to the best way possible. My team in general is already fast enough from Greninja+Alakazam to priority moves so I figured Choice Specs and Modest nature would benefit more then Scarf on Chandelure. Likes to trap all sorts of threats and either cripple them or wipe them off the face of the planet. Chose Flamethrower over Fire Blast for accuracy reasons. I almost always miss those moves (even moves like Leech Seed) so I am not taking the chances.

Alakazam needs Focus Blast somewhere on the set, preferably over Energy Ball or Dazzling Gleam, to hit Steels harder than Shadow Ball would. Then again, regular Alakazam is better because of Magic Guard's utility of avoiding recoil damage (it's fine if you don't want to, though):
-Psychic/Psyshock
-Focus Blast
-Shadow Ball/Signal Beam
-Hidden Power (Fire/Ice)/Dazzling Gleam/Substitute
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Focus Sash/Life Orb
Ability: Magic Guard

As tempting as Shuckle's high defenses are, it can't do much back. It's easy Taunt bait as well. Galvantula gained Sticky Web as well and it poses an offensive threat:
-Sticky Web
-Thunder
-Bug Buzz
-Volt Switch/Giga Drain/Energy Ball/Hidden Power (Ice/Fire)
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb/Focus Sash
Ability: Compound Eyes

Dual hazard setting is better left to Ferrothorn, tbh, because it still hits hard with STAB Gyro Ball and Power Whip:
-Spikes/Stealth Rock
-Leech Seed/Stealth Rock
-Power Whip/Protect
-Gyro Ball/Thunder Wave
Nature: Relaxed
EVs: 252 HP/48 Def/208 SDef
Item: Leftovers

Shadow Tag Chandelure was NEVER released at all during Gen V. In Gen VI, it gained Infiltrator as another DW ability, but I'm not sure if it would replace Shadow Tag completely. The best Shadow Tag users in Gen VI at the moment are Wobbuffet and Mega Gengar, but I'd use Mega Gengar if I were you, since it's stronger and faster than Chandelure:
-Shadow Ball
-Sludge Wave/Sludge Bomb
-Focus Blast
-Icy Wind/Thunderbolt/Hidden Power (Fire)/Destiny Bond/Protect
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe or 80 HP/252 SAtk/176 Spe
Item: Gengarite

or
-Shadow Ball/Hex
-Protect/Focus Blast/Dazzling Gleam
-Substitute/Hypnosis
-Perish Song/Taunt
Nature: Timid
EVs: 80 HP/252 SAtk/176 Spe
Item: Gengarite

or
-Shadow Ball
-Focus Blast/Sludge Bomb
-Taunt
-Destiny Bond/Substitute
Nature: Timid
EVs: 80 HP/252 SAtk/176 Spe
Item: Gengarite

or
-Substitute
-Disable
-Shadow Ball
-Focus Blast/Sludge Bomb
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Gengarite

Shadow Tag Chandelure doesnt exist and never has. Its hidden ability was changed to Infiltrator and is as thus illegal.

Something to consider on Greninja is Spikes over Extrasensory as you have Chandelure to block spin.

Heracross also outclasses Pinsir pretty much. Also you arent even using Pinsir's stab option. -.-

Three Stealth Rock weak mons isnt good. Id probably look into a Defog user which now removes hazards on both sides, kinda counterproductive if you use Spikes but it helps with 4x weak pokes if you decide to keep Pinsir.

Shuckle is also bad and needs the sand, Infestation, Rest and alot of support (i.e Heal Bell etc) to even do anything. So id probably replace it for Galvantula if you want a Sticky Web user tbh and put Stealth Rock on Donphan over Roar.

Donphan also appreciates Assurance to nail ghost types over Ice Shard who will block your spin. I also like a Sp.Def spread on it with max hp and 88 speed evs to beat slow Tars and whatnot.

Zam also probs wants Focus Blast or Hp Fire over Energy Ball which doesnt hit much tbh. Focus Blast lets you beat Heatran, Ferrothorn etc whilst HP Fire hits Scizor, Forry, Skarm and Ferro etc.

Id look into a fairy too, your team cannot really do much to dragons. Probably over Zam, Shuckle, Greninja or Chandelure. Whoever is your weakest link. Azumarril would be a goood choice as you are also rather Heatran weak. Belly Drum and Aqua Jet are also now legal so you could look into that or use a more conservative set.
