If you hate Conkel just bring a rain team with mixed Dragonite and Pelipper or bring a Chandelure or something.
I don't really think Conk is that problematic.
Well it's not healthy if you are forced to run either Chansey or Blissey to 'counter ' one mon. While Hydreigon also gets U-turn to keep momentum if the opponnent has one of the big blob's.
Besides Cloyster none of the comps shown above have perfect IV's.
If the offer is good, everything is for sale.
Most of the comps have the amazing Mnemosyne OT.
I don't tell prices so don't you dare ask how much
