>>58135606they're gonna add some pokemon with a third type and another new type, sound. The third type slot will have less effect on resistances and less effect on STAB. Previously 2-type pokemon that gain a third type will include Vibrava, Flygon, Noibat, Noivern, Jigglypuff, Wigglytuff, Igglybuff, Chimecho, Chingling, Bronzor, and Bronzong gaining Sound-type, Gyarados finally getting Dragon, Drapion getting Bug and Skorupi getting Dark, Cradily and Armaldo gaining Water, Rotom keeping Ghost in his appliance forms, Hoothoot and Noctowl gaining Psychic, Gallade gaining Fairy, and the Alola starters each gain a type; Primarina goes from Water/Fairy to Water/Fairy/Sound, Decidueye goes from Grass/Ghost to Grass/Flying/Ghost, Incineroar goes from Fire/Dark to Fire/Dark/Fighting, lol. Also plenty of other mons that get retyped normally with either pure sound (like whismur line) or sound/something else (kricketot/kricketune/chatot etc)
Trust me.
