The blue team of Pokémon Go. While easily the most popular team in the game, the majority seems to be the most butthurt. When they're not busy getting their gyms taken from them, they can be found on various forums either touting how smart they are, or calling Team Valor brainless jocks.
When encountered in the wild, the bulk of Team Mystic seems to be made up of teenagers or salty neckbeards complaining about the heat.
Team Mystic would have the White House if they spent less time calling Valor dumb.
