I am currently in a tournament using just Gen. II and I drafted Espeon for my line-up. I have quite a few move sets but this one seems to be the ones I will be using. It under-utilizes Espeon's great Sp. Attk, but it's what I can up with as the most dynamic and most frustrating for others to fight.
w/Leftovers or Focus Band (personal preference)
-Psychic (No need to explain)
-Morning Sun (Healing Espeon so you can drag out the battle)
-Toxic (Compounding poison effect is great for building up damage, plus this is great for killing dark Pokemon, like Tyranitar, Houndoom and Umbreon)
-Swagger (Why the Focus Band might be necessary due to the jacked up Attk. but confusion with heightened Attk. is good for fighting anything if the opponent is hurting itself)
