First things first, Gunk Shot, Swords Dance, and Recover are going on the blacklist. Gunk Shot isn't necessery, as Revenankh can already hit most relevant Fairy-types with Ghost-type STAB, and Earthquake, Power Whip, and Ice Punch can deal with Tapu Koko, Tapu Fini, and Tapu Bulu, respectively. Swords Dance is on the blacklist because it's overkill. Triage gives Revenankh a huge boost to its offensive potential via Priority Drain Punch, so giving it SD would be unnecessary. Finally, Moonlight is sufficient for Revenankh, so Recover is, once again, unnecessary.

Regarding Shadow Claw vs Shadow Bone, I've seen a differing views. I don't want to make a final decision quite yet, so I'll ask the following question: Is the power and secondary effect of Shadow Bone necessary to the success of Revenankh's Update? Second, no one has commented on Phantom Force and its use with Ghostium Z. Is Phantom Force a move we want to consider for Revenankh's Update?
