QUESTION, SHOULD I USE UMBREON AS MY LEAD INSTEAD OF AZELF?

You have 2 ubers in Deoxys and Garchomp. Substitute is not good on Hera. Give it stone edge. I never liked Umbreon because taunters rape it. Azelf does not have a good moveset in my opinion give it Nasty plot, flamethrower, Psychic, Explosion/grass knot. Dusky is fine, just give it Fire/Thunder/Ice punch depending on what you fear more....Scizor, Gyarados, Salamence.

you can use it on the E4, gym leaders or in most common battles on this site
it has 2 ubers

My favorite thing to say, you are mixnape weak.

Azelf isn't but only if he uses it as a sweeper instead of a lead and uses a not uber like Garchomp which is Uber and uses Scarf Flygon.
