I fail to see how dnite could threaten things like Lugia, Mewtwo or Mew (the most used ubers). Dnite can be a beast, but its much worse in ubers.
Also ML + BP umbreon can destroy an unprepared team (many people forget phazers!).
Lugia can take a 999 STAB Double-Edge, it can Reflect, and it can phaze. Its a monster tank, that can wall many things (and its also faster than Mew)
