I recommend pairing Nidoking up with a Grass type and/or a Wishpasser to get maximum mileage.
-Light
The only thing I have against this is MixTar does almost everything better. The positives to Nidoking are he is slightly faster and has some better placed resistances to get in slightly easier than mixtar. Though, a mixtar running LOrb with FBlast/Icebeam/Crunch/(Stone Edge or Equake) does the same thing but with more pop from each attacking side of the spectrum. I don't know if this was mentioned as I didn't feel like surfing through 4 pages, but just throwing out my input.
I still think its a cool set and definitely viable. Nice work with it
I'm going to try this out for some fun, it will probably do okay, but not like amazing..
You forgot Dusknoir, Gengar, Hippowdon and Tangrowth.
You justified Nidokings phail against Swampert by saying Swampert cannot come in repeatedly, I would just like to point out that neither can nidoking, much less than swampert as a matter of fact.
Also, the blissey that you cited as your example will nail you with Ice Beam for ~50% damage(not counting LO residual), switch out to swampert, and then kill you. Then blissey will come in against your special attacker and recover away the damage.
If blissey doesn't have Ice Beam, then you are not 2hkoing it.
I've never actually seen a Hitmontop this gen with Triple Kick, but I'm willing to admit that I'm wrong and that they do carry it.
Gyara's gonna get a free DD w/ this
but overall its good
