I know that Aegislash got nerfed hard, and so did Mimikyu. Did any other Pokemon get buffed/nerfed? (list moveset changes if you want, although there's a lot with the introduction of TRs)
Stat change: Aegislash Movepool changes Ability change: Koffing, Weezing Power changes, PP changes, additional effect changes, name changes (no known accuracy changes this generation) Other move changes:
Rapid Spin - 50 BP, now grants +1 Speed Multi-Attack - 120 BP Howl - Now Buffs Allies in doubles (Can someone test?) All Weight Based moves fail against Dynamax/Gigantamax Pokemon (Heavy Slam etc) King's Shield also now only reduces Attack by 1 instead of 2. Defog now removes Terrain Ally Switch can take the Healing Wish effect if it's used the turn after Healing Wish was used into a full HP target Fling can be used with Technical Records (TRs), and its power is determined by the contained move's power, or 10 for Status moves and moves with "---" power. Due to a bug, Sucker Punch will fail in Doubles in certain situations
