This idea has been rolling around in my head for a while, but since no one plays Gen I, let alone Gen I UU, I've never had a chance to use it, so this might not be as legitimate as it could be. However, I hope you will bear with me, and at least give this strategy the time of day. Toxic has been rendered useless in Gen I for a few reasons, not least because of the lack of stall, and perhaps also because it has terrible animation. However, consider the potential of Fire Spin/Clamp/Wrap + Toxic? the combo would be so deadly that your victory is so much as assured. The only thing you need is someone to be forced to switch into Toxic, and if you're faster (which Ninetales has a high chance of being in Gen I OU), you will only have to use Fire Spin 1-2 times before the Pokemon faints. That's significant. A common switch in to Ninetales would either be Starmie or Rhydon/Golem. Now, Starmie is serious business, so you don't keep your Ninetales in on him if you value your life. But if - IF, and this is highly likely, their Starmie is out of the picture, Ninetales can easily take out Rhydon or Golem. Consider the following set: Fire Spin Confuse Ray/Body Slam/Reflect Toxic Fire Blast Toxic never found its way onto Ninetales' default set on Smogon, but he may just have found his niche, if not in OU, then certainly in UU. The same could go for Charizard, who would have the set: Fire Blast Fire Spin Toxic Earthquake/Body Slam/Hyper Beam Similarly, Cloyster could do well with Toxic with the set: Toxic Clamp Ice Beam/Explosion Surf Also, Dragonite: Wrap Toxic Agility / Hyper Beam Surf / Hyper Beam / Blizzard So what do y'all think? Tauros would be a major, major problem as well, of course, but if somehow he's eliminated because either they're new or you're really good, this strategy might just be deadly, as Koga said it would be. Since there are no Steel Types in Gen I, or even any viable Poison types, Toxic is well on its way to being a legitimate strategy with which to be reckoned. I hope if I ever find myself playing RBY that I will be successful in using it, or even for that matter see others using it(!) Toxic is pretty much lame on its own in RBY, but the ramifications of Toxic + a trapping move, for all intents and purposes, have yet to be measured. Probably a good Pokemon to replace on the usual OU team would be either Exeggutor or Starmie.
