There are many stupid things I've seen. Especially Darkrai without Bad Dreams and including Dark Void. Night Shade would do good with Darkrai provided it has its stats raised appropriately in order to make a clean sweep of the opponent. In short here is one.
Darkrai (without Bad Dreams) - Dark Void, Psychic, Sleep Talk, Dream Eater.
Bro, without Bad Dreams, how can you expect to create optimum damage with Dream Eater. Anyways Dream Eater is a useless move in itself, provided the opponent is asleep. But I keep it with Bad Dreams always, never without it. And the only general damage attack you have is Psychic. Plus with Darkrai I doubt how much it can affect others except Fighting types which ARE weak to psychic. In short, even though its not too bad, it is an under-use of Darkrai. I use Black Glasses with Darkrai. Bad Dreams as ability. Dark Void, Dream Eater, Night Shade and Calm Mind.
Second shit - Smeargle (Leftovers) - Spore, Substitute, Sketch, Disable.
I mean seriously? Sleep Talk instead of Sketch and a damaging move instead of Disable. Or maybe Sword's Dance behind Substitute every time until you use Baton Pass in place of Disable (or attack yourself with a good move).
