Thanks for the rate!
Well, Espeon's not a bad idea (and I think I may test it) but really, Azelf's main role is not to keep away hazards - the fact he can taunt is just a nice bonus - his main role is to provide momentum and get a lot of surprise KOs. Azelf may have fairly weak moves but they have good coverage and the Pokemon weak to them tend not to expect them, so with the expert belt, I can get a lot of surprise KOs.
I'm also aware that Rotom-W isn't a great replacement for Genesect - nothing is really - but it was the best I could find. I do quite like the ScarfRaichi and SDefesnive Rotom-W idea, and I have considered it and will test it, I'm just worried how weak I will be to Reuniclus with Scizor gone.
