More like slightly dented, because no good player will be surprised by Sucker Punch. If a Zoroark Swords Dances as I switch in my Starmie (example) I'm not going to leave it in, I'm going to switch to Scizor, or Substitute Garchomp, or anything that can either survive a hit or avoid it entirely.
Do elaborate on how do you plan to predict a Sucker Punch in an illusion. I want whatever goggles you're using in battles to be able to tell the exact moment Zoroark is on the field. Otherwise everything else you've said is out of the window at this point.
Hmm, so now you're trying to insult the intelligence of everyone who used Zoroark, and realized its dead weight most of the time.
How high have you been on the ladder? What is your Zoroark cloaked as? What set do you use?
You sure love putting words in my mouth. If that qualifies as an "insult", I guess I must have been born yesterday. But it's okay --your word is apparently the voice of everyone's.
I don't do any "laddering" in OU for PO besides random matches if I'm looking to test a Pokemon's usability in that tier. I only ladder in Gen 5/Dream World Ubers (PokeBattleCenter, mainly) as OU in it's current state is Excadrill, Tar, Gliscor, Chomp; rinse and repeat. Generic and devoid of any life whatsoever.
My Zoroark assumes the guise of most Pokemon who wouldn't be immune/affected by common entry hazards. Although, I usually end up doing that anyway, forcing me to keep a spinner like Forretress or Starmie available. It also prefers to find a safe switch-in on something in Illusion to scare them off.
Usually running a build of:
Naive nature @Life Orb
40 Atk/218 SpA/252 Speed.
~Sucker Punch
~Flamethrower
~U-turn
~Swords Dance
Or, works as a revenge killer/scout as well if I'm scarfed:
Timid/Naive nature @Choice Scarf
4 HP/4 Atk, 252 SpA, 252 Speed
Flamethrower
Dark Pulse/Night Daze
Hidden Power Ice/Focus Blast
Grass Knot/U-turn (if Naive)
Most of the time it's disguised as Garchomp (if using the first set) - sandstorm/SR blows the disguise; usually resulting in a U-turn to get of the way. But in the clear, roasting their lovely Steel-type counters on the switch with Flamethrower always feels good. Forretress/Starmie are preferred partners to keep impending hazards out of the way. But with the weather wars lately, it's becoming a nuisance if Sandstorm is up.
But, I'm experimenting with more partners who wouldn't seem too out of place on OU teams. Toxicroak, Heracross, Infernape (if I'm leading), Scizor, Jellicent and many others I've tried to some extent. Team Preview might seem like a boon, but I love the paranoia it could cause once they see a Zoroark in the team and a well-known partner of it at the same time - only to figure out it's not necessarily my intention.
