fuck all you guys, I use venomoth
essentially venomoth is an inferior roserade. base 90 speed sleep powder + toxic spikes. roserade's defenses and special attack are higher, and STAB leaf storm is absolutely monstrous.
so why in the hell would you use venomoth? well, for his ability. no, not tinted lens, roserade still hits harder. I'm talking about venomoth's inferior ability, tinted lens. what the hell, why? well, tinted lens blocks secondary effects, the most notable ones being flinches. venomoth is essentially roserade minus the losing to jirachi part. he can bug buzz the pesky taunt azelfs, psychic the grounded poisons for decentish damage, put stuff to sleep, all the good stuff that roserade does, and he doesn't flinch.
so why the hell would anyone use roserade? well, the choice between the two guys is what type of team you are using. venomoth doesn't have to switch out against jirachi. thats IT. the extent of his advantages over roserade. he also can smack grounded poisons for decent damage without having to switch out. for teams that don't like switching, that's more than enough to justify his use. for teams that prefer to use the toxic spikes for more stallish use, roserade is far superior with its better defenses, natural cure, and better attack. if you have, say, a skarmory to come directly into jirachi, roserade is vastly superior. but if you're using your toxic spikes to neuter the waters that annoy your heavy hitting sweepers, venomoth is more suited to your team.
being the heavy offense player that I am, venomoth finds its way onto a lot of my teams <3
