Topic: Pokemon X/Y (help please...)

I quit pokemon a long time ago out of frustration of always losing. I gained some confidence and tried it again, but I stillneed help.

-What should I do with my Greninja and what should be her moveset and held item?
A greninja focuses on speed, but lacks defense. Ironically, My greninja excels at defense and have a weakness in speed.... Is it useless? Should I try and get a new one...?

(I din't want to annoy others in the other forum which is why I created this one) I'll ask MANY more questions later.

-What is the ultimate counter to a fairy type? I was thinking that iron ant thing, but decided to ask others. What should I beware when using one?

DURANT! Thats the name.... Durant....The iron ant i mentioned

What is your greninjas natureand ability.

Her Nature is Relaxed and the ability is Protean.
I learn the hard way that it does not switch her second type....

You can find everything you need on Smogon. Just search ''Pokemon -name- moveset'' in google and you will get a bunch of suggestions.

Fairy type is weak against steel and poison

@pixelheart

Aw man... I was really enjoying the Protean action, I'll find another pokemon though. I'll try suggestion right now. Thanks

What poison and steel types are most commonly used? I will try to avoid them.

Contary to what the OP said..

Greninja is the most versitile thing out there..

Think your mega venasaur is safe to bring in? Surprise, extrasensory
Mega scizor? Surprise, HP fire.
Again.. mega venasaur? Surprise! it got scald instead of surf or hydro pump. Burn

It's also very difficult to revenge kill with a movepool as big as arceus and base 122 speed.

Durant is a really good sweeper but if you need a hard counter to fairies; eviolite doublade, scizor, and excadrill. If you can get ahold of a competitive heatran, that's the bain of all fairies. Durant is really good and under appreciated, but some team support and well thought out playing is required making it tricky to use..

If you do consiture durant..

Durant @Focus Sash
252 Atk, 252 Spe, 6 Def/HP
Jolly (+Spe, -SpA) nature, Hustle ability
Hone claws
X-scissor
Iron head
Thunder Fang/Rock slide (You pick between azumaril or Charizard X for which move to run.. personally I got thunderfang since Zard X takes 50% from stealth rocks anyway while azumaril kinda just sits there and be bulky and belly drum+aqua jet.)

Back to greninja tho..

It really depends what your team needs. If you have a weakness to Scizor, ferrothorns, etc.. you can lure them into a hidden power fire greninja killing them. Whereas if you have a mega venasaur weakness you can lure it into an extrasensory.

Your greninja should be timid nature though.. Which is +Spe, -Atk,

Relaxed nature is actually +Def -Spe which is a big no no.

Do you know how to breed pokemon competitively?

...I have absolutely no idea how to breed period. ;-;
But wow, Thanks pal!
Time to get some of the pokemon you mentioned.
