>>45424836Buzzwole is bulkier than Skarmory on both sides, significantly more so physically. It's not a special wall so having poor special bulk is irrelevant when it is one of the physically bulkiest Pokémon in the game, resists the STABs of crucial physical attackers (Zygarde, Urshifu, Pheromosa, Rillaboom, Excadrill, Landorus-T etc.) and has 5 teammates to fall back on.
