Sure thing. Well, if you're training Sp Att and Speed, you'll need a Power Lens for Sp Att and a Power Bracer for speed. Coupled with Pokerus, this means you'll get 10 EVs for every pokemon you fight. For speed, I always battle Starly or fish for Magickarp with and old rod, and for Sp Att I battle Gastly in the Old Chateau. If you need to know how the power items and pokerus works, I can explain that in more detail if you like.
