Seriously, the move is awesome, but you only see it on, like, five pokemon (Gyarados, Tyranitar, Floatzel, and the occaisonal Gliscor or Houndoom). Wouldn't you think you'd see it on more sweepers or something? It prevents a pokemon's counter from using any status-inducing, phazing, or healing moves, which really are the bane of the countered pokemon. I mean, is Skarmory really that scary if it can't heal itself or phaze? What about a Blissey that can't heal or status, or a Cressilia that suffers from the same problem (on a side note, I love Taunting Houndoom >_>). And even if your sweeper still can't just kill the wall or may be threatened by attacks from the countering wall, wouldn't the absence of status and such make it easier to switch in a counter of your own or a pokemon that could set up on the wall?
I'm probably missing something, though...
