EV is short for Effort Value . Every time your pokemon wins a battle and gets
experience it gains an EV point in specific stat? Which stat does the pokemon
give a point in? Well, I will not be answering that here, there is another
guide dedicated solely to that purpose and to post it would be a waste of my
time and theirs. Okay, so each pokemon gives a point. What do these points do? Well, when you
get four in a single stat, that stat will increase by one extra when you level
up. SWEET! That means I can fight a million Bidoofs and give my Mewtwo 250,000
HP? Well, no, unfortunately. There are limits to how many EV points you can get, and this is why people EV train. Altogether, you can only have 510, and a single stat can only have 255.
Why waste those points in stats you are not going to use? My Gyarados doesnt
know any special moves, so why waste the points there? I will put them all in
to attack instead. Using EV points, you can give two stats a bonus of up to 63! Also, just to save you some time, I will tell you that you should only put 252
EV points in to a stat, even though you can put three more. Why? Because 252
is the largest number divisible by four that goes in to 255. So you would waste
3 Evs. Unfortunately, you can not stop some waste, and the EV spread people use
the most is 252 in one stat, 252 in another, and 6 in the last. This has the
minimal amount of waste.So I have to fight 252 of a certain pokemon... ok... that sounds like a lot.
Well I have some good news for you! There are ways to speed this up. There is
a rare condition your pokemon can get called POKERUS. This does not harm your
game or your pokemon in any way, it actually doubles the rate you earn EV points
at. There is also an item called the MACHO BRACE that double them again. So
each point is actually worth four. Saves a lot of time, eh?
There are also the power items that you can buy at the battle tower. I will try
to explain them. Each item adds four to the EVs you would already be getting.
So if you fight a magikarp, and have the power item for speed, you get five EV
points. In case you have the POKERUS at the same time, you add first then
double. So these are even faster then the MACHO BRACE.
Also, using EXP.Share on a pokemon makes it so the pokemon holding the EXP.Share and the pokemon who is fighting with it both gain EV's. But the problem is, Is that they both dont gain the same. The first one gains the normal amount of EV's, and the one with EXP.Share doesnt get the bonuses of created by the item the first pokemon is wearing. He gets the EV's he would if he was battling the pokemon with the items on him, (Pokerus does effect this)
To EV train effectively, you must give your pokemon PKRS disease. To do this, get 2 pokemon with pokerus put them in the 2nd and 5th spots in your inventory. Then get into a battle and switch to the 2nd pokemon, use a physical attack on them, and all your pokemon should have Pokerus now.
Second, your going to want a power item, read below to know which does what. So know what power item you need, then go to the battle tower, and duke it out with the tower brains until you can afford them. So you got your pokemon with pokerus and holding a Power item. What now?
Bidoof is probably your best option for wild Pokemon that give HP EVs.
With PKRS: 2 EVs per Bidoof defeated
With PKRS and Macho Brace: 4 EVs per Bidoof defeated
With PKRS and Power Weight: 10 EVs per Bidoof defeated
Therefor in order to get to 252 EV's in HP you'd kill 25 Bidoof's with your item on, and then kill 1 without your item. Easy as pie! And I love pie.
In the wild, Machop give one Attack EV and Bibarel give two EVs.
With PKRS: 2 EVs per Machop defeated, 4 EVs per Bibarel defeated
With PKRS and Macho Brace: 4 EVs per Machop defeated, 8 EVs per Bibarel defeated
With PKRS and Power Bracer: 10 EVs per Machop defeated, 12 EVs per Bibarel defeated
Therefor in order to get 252 EV's in ATK you would need to kill 24 Machops, and one Bibarel with PKRS and your power Item on!
I prefer Geodude and Graveler for Defense EVs.
With PKRS: 2 EVs per Geodude defeated, 4 EVs per Graveler defeated
With PKRS and Macho Brace: 4 EVs per Geodude defeated, 8 EVs per Graveler defeated
With PKRS and Power Belt: 10 EVs per Geodude defeated, 12 EVs per Graveler defeated
In order to get 252 Defense you would need to kill 24 Geodudes and 1 Graveler, With PKRS and your power Item.
In Special Attack, I generally go for Gastly (1 EV) and Roselia (2 EVs) in the wild.
With PKRS: 2 EVs per Gastly defeated
With PKRS and Macho Brace: 4 EVs per Gastly defeated
With PKRS and Power Lens: 10 EVs per Gastly defeated
To get 252 Sp.Atk you would need to kill 25 Gastlys with PKRS and Powerlens, and 1 Gastly with just PKRS.
Tentacool is just about the only way to go in the wild without having to deal with dongling, PokeRadar, swarms, or version-exclusive Pokemon. Mantyke and Mime Jr. are OK as well.
With PKRS: 2 EVs per Tentacool defeated
With PKRS and Macho Brace: 4 EVs per Tentacool defeated
With PKRS and Power Band: 10 EVs per Tentacool defeated In order to get 252 special defense you need to kill 25 Tantacools with PKRS and PowerBand, and 2 without Power Band or any item on.
Magikarp is everywhere, and Staravia's pretty common, too.
With PKRS: 2 EVs per Magikarp defeated, 4 EVs per Staravia defeated
With PKRS and Macho Brace: 4 EVs per Magikarp defeated, 8 EVs per Staravia defeated
With PKRS and Power Anklet: 10 EVs per Magikarp defeated, 12 EVs per Staravia defeated
In Order to get 252 speed, you have to kill 24 Magikarps, and 1 Staravia with PKRS and PowerAnklet.
