Oh look, this conversation is still going on.
Lets bring up some more points that I originally didn't mention, shall we?
Safeguard prevents status
Aromatisse has the ability Aroma Veil which completely kills confusion and foulplay is resisted. This Pokemon, given that fact, can whittle their hp down as they spend subs or get destroyed by moonblast
Disregard that, I suck cocks.
If you use a special attacker and put 0 in ivs under attack, they cant do damage for shit
Natural Cure is a great counter, they can par you all you want and yet when you switch, not only do you get rid of confusion and swagger boosts, but you get rid of the par too.
Limber completely negates thunderwave.
Electric types are immune to thunderwave.
Ground types cant be para'd.
Taunt can ruin an entire team. Sound based moves and multihit moves along with infiltrator cant ruin the entire team.
Not to mention magic bounce and syncronise can destroy the entire team. Mental herb and lum berry can open up a free opportunity to kill.
The Pokemon can snap out of confusion on the first time and sweep
The Pokemon can have own tempo on Pokemon even as abundant as Smeargle.
Pranksters kill other pranksters with ease.
Switching gets rid of confusion.
Any bulky Pokemon with low attack can cause a Pokemon to stall out and struggle.
Heracross is an excellent counter given that you don't hit yourself. It 4X resists foulplay, has access to mega horn and if that doesn't tickle your fancy, mega pin missile is a good way to not only do super effective against purrlion, liepard, sableye and other dark types, its a multihit move so it passes through subs (Plus the fact that skill link lets it hit 5 times in a row).
Sylveon is an AMAZING counter, with low attack, and fairy typing it can not only effectively resist foulplay but it HAS ACESS TO PIXELATE + HYPER VOICE, RENDERING SUBS USLESS AND PASSING THROUGH SUBS TO KILL NOT ONLY THE POKEMON HERACROSS CAN, BUT MURKROW INCLUDED.
I've said it before, but INFILTRATOR.
Priority moves if you out speed, if not, par them, then they no longer out speed in priority
Knock off takes away leftovers, soon they'll run out of hp for subs, leaving them vulnerable.
Whismicott not only resists with fairy typing, but it ALSO has
prankster, giving it the power to possibly outspeed (if not, whim can par them), sap their hp with leech seed AND get behind a sub so swagger and thunderwave cant hit it, along with the fact that foulplay and poor attack makes it hard to get past.
Substitutes get rid of the problem of para and swagger.
Hazards can take their hp to dangerously low levels.
Toxic spikes limit's Purrlion and Liepard's time on the field
Confuse a Prankster, watch the fun!
I think I'll stop there. Banning something beacuse you think its annoying (or god forbid you carry taunt not my single move slot no!) is Smogoning out. The same deal with funbro, if you start to struggle, you lost, if he wanted, he could let you die and it would be gg, but he's doing it to carry on, which means a forfeit isn't going to do any difference. Funbro is also destroyed and countered by special attackers and ghost types but who needs to switch on the turn it comes out anyway?
There's alot of reasons I dont like Smogon, this is one of them. The moment you ban it, the moment it effects everyone because everyone follows your rules.
