Even if you can't spin, it's going to come in 3 times and most likely KO 3 things. Barely anything can take its Bug Buzz because of all of the other mons that are stuck in UU who usually counter it.
Venomoth is uncompetitive in my opinion, but otherwise just simply broken. Without considering Sleep Powder, Venomoth is still too hard to handle due to its moderate bulk, Speed, and power. Sleep Powder + Quiver Dance is kind of absurd because you basically have a .75x1x.5.x.33 (iirc that's how sleep works...) chance to win the game right then and there.
Omastar: Don't Ban
Oh hell no, this thing is pretty lame. Shell Smash users are very overrated but especially Omastar who is actually weak to the ever-common Mach Punch. It's not that fast either, some Scarfers outpace it.
This thing is more legit than Omastar because it doesn't have that ridiculous Mach Punch weakness, but still after a Shell Smash a tickle of a priority attack will kill it. The best Shell Smashers are all weak to Electric, fyi.
Read above. Literally the exact same opinion, same problems, same strengths.
