Now, Effort Value Training, or EV Training, can be a long and tedious process that many people either don't know how to do, or can't be bothered to do it. But, what those people don't know is that EV Training can be very easy as long as it is planned out.
EVs: the breakdown
Now, each Pokemon can have a grand total of 510 EV points, with a max of 255 per stat. Every 4 EV points=1 stat point. So, the greatest number divisible by 4 out of 255 is 252, with 3 EV points left over. 252/4=63, so that's a major amount a stat can increase, which can easily tip the scales in one's favor in a battle, competitive or not. Each Pokemon gives a certain number of EV points, ranging from 1 to 3, in one or more stats.
"But, if I fight a pokemon with only 1 EV point, that means I'll have to do 252 battles!" Actually, that is the worst thing anyone would want to do. Who would want to do 252 battles just to make a Pokemon's stats go up by 63? It just is not a fair trade-off. This is where vitamins come in. Vitamins raise a certain stat's EV Points by 10, and a Pokemon can be given a max of 10 vitamins per any particular stat, so that's 100/252 already taken care of. Vitamins can be bought at the Veilstone Department store for a whopping 9,800 each! But who has that much money? So, Nintendo felt generous and decided to place Vitamins in random spots around the games. They can also be bought at the Battle Frontier for 1 Battle Point(BP). How cheap!
Pokerus: Why its your best friend
Pokerus, the Pokemon Virus, can only be obtained one of two ways: 1. Get it from a trade on the GTS. 2. Obtain it from battling wild/Trainer Pokemon repeatedly until you have it. Pokerus is essential for EV training, but it is not required. Pokerus doubles the amount of EVs received at the end of a battle, effectively turning 1=2, 2=4, and 3=6. Once you have Pokerus, it will eventually spread to your entire team through battling. Pokerus disappears after 24 hours, so keep at least one infected Pokemon in the PC so you can keep it forever, thus saving you from doing more tireless battling.
Macho Brace and the Power Items
The Macho Brace is an Item obtained from a person in Pastoria City after showing them all 3 formes of Burmy. It doubles the amount of EVs received at the end of battle at the cost of cutting your speed in half, but works before Pokerus does, stacking up like this: 1=4, 2=8, and 3=12. The Power Items are obtained at the Battle Frontier for 48 BP, and add 4 EVs to the respective stat at the end of battle at the cost of cutting your speed in half, but works before Pokerus does, stacking up like this: 1=10, 2=12, 3=14. If anything is required in EV training, its the Macho Brace/Power Items, because they are way easier to obtain compared to Pokerus.
Now that the basics are covered, its time for the equations that help with EV Training, detailed in each stat. I will not cover Pokemon that give 3 EV points, as they are too hard to come by, nor will I tackle any Pokemon that give EVs in more than one stat, as they are harder to control. I will be giving a guide using Pokemon that only give 2 EVs for only one stat, because they are easy to find and it will be roughly the same as using 1 EV givers, only twice as fast. The equations are for the most commonly used EVs. I'll be telling you which Pokemon are easiest to find. I'll also say which item is best to be used.
HP Stat
Pokemon to Battle: Clefairy, Chansey, Noctowl, Quagsire, Whiscash, Sealeo, Gastrodon
252 EV Points(Pokerus and Macho Brace give san EV of 8 at the end of the battle when using Pokerus against a 2 EV giver, Power Item gives12):
1. Add 10 HP Ups.
2. Equip Power Weight/Macho Brace
3. Do 12 battles with Power Item, 2 without/MB=19 battles
252 EV Points(Without Pokerus. Using Power Item{gives 6})
1. Add the 10 HP Ups
2. Equip Power Weight
3. Do 25 battles with the PI, 1 without it
180 EV Points (With Pokerus, Power Item/Macho Brace)
1. Add the 10 HP Ups
2. Equip Power Weight/Macho Brace
3. Do 6 battles with PI, 2 without/MB=10 battles
180 EV Points(Without Pokerus. using Power Item)
1. Add the 10 HP Ups
2. Equip the Power Weight
3. Do 13 battles with the PI, 1 without it.
150 EV Points(With Pokerus, Power Item/Macho Brace)
1. Add the 10 HP Ups
2. Equip the Power Weight/Macho Brace
3. Do 4 battles with the PI, 1 without/MB= 6 battles, 1 without MB
150 EV Points(Without Pokerus. Using Power Item)
1. Add the 10 Hp Ups
2. Equip the Power Item
3. Do 8 battles with the PI, 1 without
Attack Stat
Pokemon to Battle: Machoke, Weepinbell, Gyarados, Dragonair, Absol, Luxio
Essentially, do the exact same thing as you did for HP, only replace the Pokemon with the ATK ones, use the Power Bracer, and add Protein.
Defense Stat
Pokemon to Battle: Graveler, Steelix, Magcargo, Skarmory, Pelipper, Torkoal,
Essentially, do the exact same thing as HP, only replace the Pokemon with the DEF ones, use the Power Belt, and add Iron.
Speed Stat
Pokemon to Battle: Raticate, Fearow, Pikachu, Golbat, Poliwhirl, Medicham, Staravia, Floatzel
Essentially, do the exact same thing as HP, only replace the Pokemon with the SPE ones, use the Power Anklet, and add Carbos.
Special Attack Stat
Pokemon to Batte: Gloom, Golduck, Kadabra, Girafarig, Roselia
Essentially, do the exact same thing as HP, only replace the Pokemon with the SP.A ones, use the Power Lens, and add Calcium.
Special Defense Stat
Pokemon to Battle: Tentacruel
Essentially, do the exact same thing as HP, only replace the Pokemon with the SP.D ones, use the Power Band, and add Zinc.
_________________________________
Okay, I know that got repetitive, but that's all you have to do. All of the Pokemon can be found in the wild, and I tried to use ones that ARE NOT required to be used by an in-game Trainer. But, this is EV training in a nutshell, and its what I use(other people probably use it too).
Also, if you want to use different EVs, all you have to do is get a calculator, type in how many EV Points you want(between 1 and 63), multiply by 4, and there you go. then, divide by 8 or 6(depending on if you are using Pokerus or not), and if its a whole number, that's an exact number of battles. If its a decimal, see the closest number to that divisible by 4, see if its divisible by8/6, then that determines if you have to take of the Item/Macho Brace.
EDIT: fixed the pokerus equations
EDIT2: Since PI+PKRS=10 EVs from a 1 EV pokemon:
HP=Bidoof
ATK=Machop/SHINX
DEF=Geodude
SPE=Starly
SP.A=Gastly
SP.D=Tentacool
In case anyone wanted an easier time training, the 1 EVs are listed above, and are found at much lower levels. Just tweak the equations by replacing the 2 with a 1, or the 12 with 10, and do a bit more math(there's a calculator app one the poketch).
