Pokémon X & Y super training ?

[BumblebeeCody*]

One more question - If I'm at level 50, and suddenly decide I want to max out my HP EV, will that bump up the HP immediately ?
Just a point of curiosity, as I'm not going to do much EV training (and will therefore avoid online battles as I expect people take this very seriously) !

Yeah but so long as you haven't maxed out your EVs. It's worth noting that it's no possible to EV train after at level 100 in the games before (and including) Diamond/Pearl/Platinum. -> Additional shit that's not really important.
The the older games you only ever gained EVs through leveling. However after Diamond and Pearl with the release of the B/W series, you can EV train at any level. What makes the older games slightly funner(word?) though is that you since you only gained(well confirmed) you EV training at each level up, you could EV train everything within one level and end up with a level up results screen like this:


If you wan to train at level 1 you can. If you want to train at level 50 you can and the same applies to level 100. 

You can actually try this yourself. 
Go to any Pokemon that hasn't been EV trained
Check their stats
Give them 10 HP UPs (these give 10 HP EVs) 
Then watch as their stats increase on the Pokemon selection screen. You can do this for all other stat boosting items.

Additional EV stuff
(Only if you're interested)
On the topic of stat boosting items, these are also important.
Each of the following Vitamins boost your Pokemons stats by 10 EVs.
Vitamins:c
Item
Effect on EVs

HP Up
+10 Hit Point EVs

Protein
+10 Attack EVs

Iron
+10 Defence EVs

Calcium
+10 Special Attack EVs

Zinc
+10 Special Defence EVs

Carbos
+10 Speed EVs


Since this is Nintendo we're dealing with, they're still stuck in the 90's and their 90's ways. You can only give a Pokemon 10 of each vitamins. To go back to the Lucario example. You can give Lucario an easy 100 EVs in Attack by giving him/her 10 Protein vitamins. After that you have to train the rest. However you can also give the Lucario 10 Carbos's to give to give it 100 in speed. I don't understand the point of the level cap but ....Nintendo....they added tripping in Brawl and removed Snaking in Mario Kart so. Eh.


Wings: 

Health Wing
+1 Hit Point EV

Muscle Wing
+1 Attack EV

Resist Wing
+1 Defence EV

Genius Wing
+1 Special Attack EV

Clever Wing
+1 Special Defence EV

Swift Wing
+1 Speed EV


Wings give you 1 EV in each stat. However there is no cap on using these. So get 252 of these and spam them for each respective stat. 

Berries:

Pomeg Berry
-10 Hit Point EVs

Kelpsy Berry
-10 Attack EVs

Qualot Berry
-10 Defence EVs

Hondew Berry
-10 Special Attack EVs

Grepa Berry
-10 Special Defence EVs

Tamato Berry
-10 Speed EVs



If you accidentally give a Pokemon certain EVs in a stat you didn't want ("Oh no I beat a Mime Jr with Lucario now I have 1 EV in Sp.Defence") these berries will rid that stat of 10 EVs and raise it's happiness. 

Sorry for the essays but it's worth knowing this kinda of information. EV training is hard to explain so I may as well talk indepth about it. There's still so much more I haven't talked about but I'm keeping it simple here.
