I guess you could try something like this, if you are not afraid of unleashing the wrath of g-stunfisk upon an unsuspecting OU.
With this set you can trap g slowking, pex(if it doesn't get a scald burn on the first try), maybe clef(snap into EQ into steel beam will probably kill it if it doesn't heal or set up cm, or yawn into double steel beam), melmetal without EQ, nidoking, tran, hilariously own hippo since it can't do anything to you, do the same to zapdos without heat wave(just EQ when it goes for roost), and you can even take out regular slowking with snap trap, EQ,EQ if it tries to come in on you and fight you in vain, aegislash(with this spread unboosted fully invested ada cc does 99.7% and you can OHKO blade form with EQ), ttar if it tries to switch into you with a bit of chip,excadrill, you have a 25% chance to OHKO weavile with steel beam, while it cant OHKO you back, and you can guaranteed put ferro and some dnite(if it switches into you) to sleep.
Now a lot of this depends on the opponent giving you an opening, but come on its g-stunfisk you gotta hope they play it a bit dumb.
