Ok, I want to bring priority moves into the light because those are super important. Mainly I think that shadow sneak and Sucker Punch should be allowed. (sorry if I am beating a dead horse with sucer puncch since "all dark type moves" are already allowed but you also said "nothing was written in stone"). Anyway,this is because of main threats like Gengar and latios/latias. Shadow sneak allows for CAP5 to 2HKO Gengar because of it's priority. Normally Gengar would be able to 2HKO CAP5 with focus blast and maybe even HP fire but shadow sneak fixes this problem completely. As for sucker punch, which is much more OP in retrospect, can OHKO such threats as CM latios/latias and bulky Jellicent but requires very precise prediction because it won't hit unless an attack is coming, making it much less OP in my opinion. I also think that Fire type moves and ground type moves with over 60BP should be disallowed because take into consideration a Scizor using sword dance in front of a grass/dark Pokemon thinking it will have no trouble OHKOing it at all when BAM a fire fang to the face wrecks it. Way too OP, Scizor is supposed to be on the "threatened by" list. On another note, I would like make an argument that we should discuss Icicle spear as a competitive attacking move and as a good ice move despite not being 60 BP or more. This is because of it's ability to break substitute making it more important then normal. Also, I think being a multiple-hit move does TECHNICALLY give it a total BP of 125 (max). I won't discuss it any further than that though.
