Umbreon, when raised properly, is a friggen TANK! I don't have room for one on my current team on White because I already have a Dark Pokemon, Zoroark (though I did manage to trade for an Eevee through a different forum =D (Maybe raise it to an Espeon? Haven't figured it out yet.)). Not that I do much competitive battling, but hey, when you can sweep through the Elite Four with ease, IMHO, it's worth having a well-raised team.
