So I might just go back to my roots and go with an NU balanced team for UU:
Seeing there is a bit of talk about Cacturne, the cactus-funny looking guy <_< Is Sandstorm an essential move to use? Because of it's sand veil?
Seeing that Alakazam is the reason why Espeon is NU now...
Alakazam is a frailer, faster, slightly stronger Espeon with Focus Blast, Taunt and Encore, but no Baton Pass.
Basically that's all the differences about Alakazam and Espeon. So people use the best one... Alakazam it is.
Really: if you want to use Espeon, use Baton Pass.
Because Espeon is NU and that earns you coolness points. :P
Some of the things that caught my eye were his great 40/130/130 defenses (better than Spiritomb mind you, but without the better typing),
I just realized recently (don't laugh -_-) that Magcargo, yes, I repeat, Magcargo, walls quite a couple things in UU that are often used. Not saying its a good poke, but it definitely can murder the daylights out of some pokemon if somehow you can b-pass mean look. Froslass, Scyther, Moltres (unless it has hp ground), Swellow (eh, too bad it usually runs u-turn), and the sets of Venusaur that don't run EQ or HP ground. I'm not sure if other people have seen this before, but i'm guessing this will be unsuccessful in most situations...
