1. Find a damage calc. Thunder does indeed do ass.
2. Nasty Plot vacuum wave does like 75%, so with pretty much any residual damage it loses. Also this Toxicroak has Focus Blast which OHKO's with no nasty plot.
3. Does it matter about switching in ? When he can revenge kill it with like his whole team team if it lives somehow lol.
4. No one uses thunder so there in no point in arguing, its a novelty set thus is a moot weakness. Its like saying "You are weak to fear rattata">_>
^ My main point anyways, so yeah.
(Also if you are trolling, its kinda not funny and no one is impressed nor does it make you look good, just saying ;))
