Scizor with Flame Wheel. Zekrom with Earthquake. Kyurem-B with Earthquake and Icicle Crash. Genesect with Hydro Pump and/or Waterfall... And a lot more physical moves. Keldeo with more than 8 Special moves.
I'm not easily impressed; I'm usually oblivious to whatever's in front of me.
Keldeo and Seismitoad with Ice Beam. Flareon with Blaze Kick (because the recoil from Flare Blitz would kill it). Flareon with Solarbeam. Flareon with Wild Charge (extremely unlikely but Arcanine does get it). Blaziken with Extremespeed (would have been better before it had Speed Boost). Pidgeot with Extremespeed (still probably wouldn't make it OU/UU level). Weavile with Close Combat.
Generation 30: The first time you see this, copy it into your own signature (on any forum) and add one to the generation number. Social experiment.
