I'm wondering which is more useful.
Wonder Skin allows you to Baton Pass and stat boost without having to worry as much about Taunt. And Roar/Whirlwind will also be less likely to hit Venomoth. However, the Pokemon Venomoth passes to can still be hit by Roar/Whirlwind, and it doesn't block Dragon Tail/Circle Throw. Thunder Wave/Glare are also less effective. Wonder Skin also only makes these move have a 50% chance, not a 0% chance. So with luck, these moves can still get Venomoth.
Tinted Lens allows Venomoth to make good use of its Quiver Dances, and since Venomoth can run Wonder Skin, your opponent might not use Taunt, Roar, Whirlwind, Thunder Wave, or Glare on you anyways. At least not until your opponent uses a damage calculator. This helps for when it is not safe to pass, or can be used to catch a foe off-guard.
