>>57879807I've used Venomoth before. It's not great. Imo the evolution is massively too late (fucking lvl 32) for you to ever consider actually raising a venonat up, but in FR/LG you can catch one at like level 40 in the sevii islands, and then you have basically a slightly slower but better at everything else Butterfree. Which at that point of the game isn't that great! Idk man there's not much to say.
>>57880432Solid HM Slave in gen 4 if you don't want to use a Bibarel.
>>57880615Dewgong is sorta fucked in Kanto given the free Lapras you get which is just better and available earlier. Not really a reason to use it anywhere else either (it has pretty ass availability too). Sucks honestly, it could use an evo
Muk's fine (though alolan has better typing)
And yeah putting Ninetails here is weird as fuck like the other guy said
