Two Ground-type Pokemon, eh?
Nidoqueen’s unique typing and natural bulk accompanied with the recommended EVs form a wall against the plethora of Fighting-types in today’s metagame, such as Lucario and Toxicroak. The moves provided assemble these characteristics into an effective stall breaker, via tainting the opponents field with Toxic Spikes and futher exploiting them with Dragon Tail. However, you may opt for Fire Blast as a response to rampant Steel-types like Ferrothorn, Scizor, and Skarmory which otherwise switch in undaunted.
Moreover, Super Fang aids in clearing the opponent’s team of defensive buffers and will consistently break opposing substitutes - creating a problem for Ninjask. Despite the leverage afforded by Super Fang, Ice Beam maintains coverage on rival Ground-types and gives an edge against Nidoqueen’s OU likeness: Gliscor, who has access to a reliable recovery move and an immunity to Ground; things Nidoqueen lacks.
And Earthquake tops off the set with STAB.
Now, if you didn’t know, I’m very lazy. You submitted two Pokemon, so I built you an original Nidoqueen moveset, but, as for Golurk, it’s just a common Choice Band set from Smogon.
Thanks for the message.
