:/weeeeell in response to ByakuganBodmon, i think umbreon is pleanty good enough to be a wall, I use mine as a wall, and it can stall out life orbed electivires cross chop and all very well, the only pokemon that really posed a problem for it wall wise is lucario, (machamp which i dont see often...), and x scissor on sword danced ninjask( . everything else, isnt too bad. Umbreon to me, is to good to be in uu/bl because it can be used so many ways. I use one as a lead, with defensive/hp ev's and moveset: taunt, payback, protect,wish( wish would work GREAT with the addition of sucker punch instead of payback, cause if a taunted poke like ninjask, gyarados, salamance etc, they will, either attack you, or switch and it will either hurt them, or do nothing either way its as benefit.) and you can costumize it any way you want. it is one of the best mean look passers because of its defensive capibilities , a great staller, and with a few curses can take just about anything out with wish and payback combo, and sucker punch also makes the curse umbreon awesome , because it can strike first, and be as slow as heck :D!. I cant see many uu/bl pokemon having a fun time with it any which way.
as for the easy switch in for lucario, yea, a fighting typed stab move, its gonna hurt, just like someone having a magnezone, jolteon or electivire switch into there gyarados, starmi, vaporeon, etc, its gonna hurt and mess up there team, doesnt keep them from OU does it?
