Section One (How to EV train your Level 100 Pokemon in Generation Four.)

Step 1) Use stat reducing berries (Pomeg for HP, Kelpsy for Attack, Qualot for Defense, Hondew for Special Attack, Grepa for Special Defense, Tamato for Speed), and remove ALL of your Pokemon's Effort Points.

Step 2) Give you Pokemon one Effort Point in a stat that it will NOT be needing it in.

Step 3) EV train your Pokemon, as usual, with either vitamins or through battling. Be sure to give it ALL of the Effort Points in ALL of the stats you will want them to be in, or you will have to start these steps over again.

Step 4) Remove the one extra Effort point you gave your Pokemon. Upon completion of these four steps, you will have successfully EV trained your level 100 pokemon with the stats you want it to have.
