Gdi! Ain't gonna edit with phone ever -___-' That aside, could you, please fix the AC part about SR switch-ins. Moltress isn't NU as far as I know, or is it? So you could mention something like Mortar or Rotom-s there. And...sorry, again...
An OO mention is probably the best bet, mentioning that as a defensive Poison-type it can absorb Toxic Spikes (which is its only real merit over Weezing, imo). There are just other, better Poison-types that can pull off a defensive-ish set, like Garbodor or Muk or Weezing. The additional Speed or power really doesn't mean too much when you aren't investing in either. Arbok's real niche is a pretty good Coil set and Shed Skin, so we should just keep it to that I think.
Thanks. Sorry, I kind of dropped off without warning because of college, I haven't had much time at all since I've been making up for being sick for a week and a half.
Btw, you might want to double-check if those sets are even viable in the current meta, the analysis was originally made back during the December metagame. I can help with that if you like, though I'm probably pretty rusty.
