Pokemon help!

EV trainings very very complex. Best explination I have heard is think of 1 EV as 1 heart piece from legend of zelda. 4 Evs equal 1 stat. Example, you kill 4 guys that give you 1 EV in attack each you will get one more stat in attack the next time you level up. I would send you a link but I cant yet but check this site called seribi.com they have some good information for all that sort of stuff.

Those are kind of difficult to explain but i'll try. Ev training is like when you battle certain pokemon that can make your pokemon better in attack,spec.attack,etc. So for example if you have your pokemon battle a fast pokemon it's speed would go up higher then normal.
