I fail to see how ORAS NU is the same as XY NU, given that Quagsire, Mawile and Claydol dropped, a lot of mons left(Slurpuff, Sceptile, Pangoro, Dragalge, Steelix, and that's just the more relevant ones, not even going to dig into the likes of Beedrill), and stuff like Gatr, Typhlosion, Audino and Kecleon got big buffs as well(and if the former two get banned that's even a bigger change since they absolutely ruled the show in XY.)
also if you feel like blaming someone for this anyway, don't blame the council. At most they banned mons bound to rise regardless.
