Ok, so its been a long time since my previous blog Pt1. So I'll continue with it and do a little more explaining.
For starters the main reason for EV training a pokemon is to greatly increase the stats of the pokemon. Like I said in my last blog, the damage delt to a pokemon is not determined by it's level, but its stats. And the best way to explain this is by example.
Lets say I have a Metagross. And I want a really powerful one! But the one I have is weak and faints quickly, what can I do? EV train a new one. (Just a heads up, you cannot EV train a pokemon that is level 100, it must be new and have no experience points.) So the first thing I do is get a Metagross egg, by catching a new Beldum (Its first form) After I have the one I want to train, I give it the macho brace to hold, then infect it with PKRS by getting a pokemon with PKRS and switching out with the Beldum in waiting. Then quickly run away, (WITHOUT KILLING ANYTHING) and check to see if its infected.
Once its infected and is holding a Macho Brace, I need to figure out what stat I want to be uberly massive. Since I want a powerful one, I'll just EV train its Attack stat. So I go to place where I can buy Proteins. I buy 10, and use them on Beldum. (Proteins boost attack stat, but only use 10.)
Ok so my Beldum is infected, holding the Macho Brace, and has 10 proteins in its attack stat. Time to begin training. This next part is very confusing. When you are EV training a pokemon to boost it's stats, you can only get 252 EVs into a single stat. Each pokemon can get 510 EVs, that means (If you do the math) 510 minus 252 = 258. That means for each pokemon you EV train, you can raise 2 of its stats! With 6 EVs left over!
Here's where the magic comes in, I want 252 EVs in my Beldum's attack so when its fully evolved it will be REALLY strong! So 10 proteins = 100 EVs. 100 EVs minus 252 = 152. So with the 10 EVs I gave my Beldum earlier, it now has 152 EVs in attack. Time to do the REAL training
