Ok first you click on the list of pokemon, and type in the level, then it comes up the stats. The highest stats you can have is at the right the lowest left. Each 4 ev count as one stat. If you have more problems tell me!
Here is the lead of my team:
Uxie @ Leftovers
Bold Nature ; 255 HP/ 255 SpD
~Light Screen
~Stealth Rock
~Reflect
~Giga Drain
This is my lead most of the times. Put up a light screen and reflect, then switch or if Uxie took some damage drain the enemy. If Uxie is trapped or is the last of the crew then just giga drain to damage the foe. He is ultimate Swampert slayer.
