in balanced hackmons there r banned abilities like huge power which make sense cuz that ability break balance but there is abilities that should be banned cuz they break balance or just prevent a players to play and the abilities that i think should be banned are fur coat and ice scales and simple and normalize and impostor. first is fur coat and ice scales and its cuz of fur coat double ps defense while ice scales halve damage taken from special moves which means having one of those abilities will double one of the defenses so imagine facing a fur coat evolite chansey (that is a nightmare) and fur coat is effectively huge power if body press was used and even worse the best defense stat is more than the best attacking stat in the game and if the foe have the right doubling defense ability the player will maybe cant inflict good damage. second is simple cuz power herp geomancy is everywhere (its self explanatory). third is impostor cuz the problems scarf ditto do to me in natdex will of course follow me in any format and normalize is for the annoying strat of a ghost type entertamienting me into normalize and other sloth (i dont know how to spell it or type it right) and foresight dont exsist in gen 8 and balanced hackmons use mons and moves that are only in sword and shield.
