One of the key features of Pokémon GO is its trio of teams. Niantic's hit mobile game has you choose early on between Team Instinct, Team Mystic, and Team Valor, and from then on you'll be claiming gyms in the name of your team and battling against opposing gyms. In the past, your choice of team was a permanent decision, but soon that won't be the case.
If you're getting tired of your current team colors and want to switch things up, you'll be able to do so starting on February 26th. Niantic is launching a new "Team Medallion" item that lets you change your team loyalty, but there are some strings attached. This action can only be performed once every 365 days. More importantly, a Team Medallion will cost you 1,000 PokéCoins. For reference, $10 gets you 1,200 PokéCoins in the shop, so this isn't exactly a cheap decision to make, considering this is a free-to-play game.
