lol you really don't get it, do you? You aren't taken seriously because of this precisely - you don't even check Bullet Punch's damage (and btw since when does ground resist steel >_>) yet you try to sell it to us. You clearly haven't tested it either. But if you want the calc:
788 Atk vs 190 Def & 304 HP (60 Base Power): 348 - 411 (114.47% - 135.20%)
Easy OHKO.
"Revenge killing" CBers is absurd (especially one like Scizor) when the whole purpose of a choice item pokemon is hit and run. Besides, I know you've "only seen" CB sets, but CB is on less than 8% of Salamence (which, if its own pokemon, is easily BL). CB is on 29% of Scizor, and while that would be OU alone, it's still pretty low (while LO is on 43%) and Swords Dance Bullet Punch is on 62% of Scizors, which will at the very least severely damage Nidoking (even without a LO Bullet Punch OHKOs 59% of the time with SR down). ScarfTran actually revenge kills Scizor rather than folding to Bullet Punch, and it also beats non-DDmence (and btw DD is on 48% of Salamence) without locking itself into an unSTABed Outrage. Likewise, it can catch DDmence Outraging after a DD, take the hit, and kill it. It also revenge kills other Heatran bar ScarfTran locked in on Earth Power, which half the metagame sets up on anyways (Gengar, Zapdos, Gyarados, Salamence, etc.)
Blissey coming in on you probably sounds absurd but it actually isn't.
311 Atk vs 119 Def & 651 HP (90 Base Power): 169 - 199 (25.96% - 30.57%)
Outrage on Calm 252 Def/0 HP Blissey given the negative rivalry effect. now it can actually switch in on and beat a physical attacker. I'll let that sink in. You're stuck on Outrage so you're at least taking one Ice Beam, maybe a second one to finish you off. It can also Softboiled if you get something like a crit too. What about STAB EQ?
311 Atk vs 119 Def & 651 HP (75 Base Power): 211 - 249 (32.41% - 38.25%)
Still stalled out by a BLISSEY. imagine what happens when something with more than 10 base Def shows up.
As for:
"People treat nido as setup fodder anyways and I don't know any heatran that switches out of nidoking."
Just because people treat Nidoking as a set-up fodder in OUs doesn't give you an excuse to make it even more of one. there's a reason nobody uses Nidoking in OUs: because it sucks. Hell ScarfGar is a better choice than this seeing as it does more to Blissey with special attacks than Nidoking will do to it with Outrage.
Also, let's say Scarftran revenge kills Lucario with Earth Power or Fire Blast or whatever...if you bring in Nidoking, it almost totally gives away that it's scarfed because Nidoking is an awful way to deal with the common ScarfTran. Even Fire Blast does a lot:
359 Atk vs 186 Def & 304 HP (120 Base Power): 249 - 294 (81.91% - 96.71%)
So it's essentially a dead giveaway since taking 97% damage would be very foolish. Besides, what do you mean people don't switch Heatran out? the only time you would get a kill is if they thought you were a slow Nidoking (not likely though due to its low damage output which would rule out CB in a smart player's mind) and tried to revenge kill you...but for the reason just stated it probably wouldn't happen...damage output gives it away. I mean who leaves something 4x weak to the opponent's STAB attack in to take the hit? That's just rubbish ._.
And you can accuse Vance of being out to get you all you want, but I can assure you it's just because he doesn't take you seriously: he doesn't have anything against you, he just thinks you aren't somebody to be taken seriously. I know you won't believe that but it's actually true >_>;
So yes, that's what I meant by faulty logic. If you want people to take you seriously, go to Smogon and get good using bog standard pokemon (not this novelty garbage that doesn't work) and learn to play. You also need to actually think things through before posting them and test these sets out. You assume things that don't make sense and practically defy logic and you say people are out to get you. Get good, check your facts before posting, and then you can come chat to me about Vance. Because right now, you don't really have any ground to stand on >_<
