This particular competition format within the Pokmon GO battling system provides a unique twist by restricting eligible Pokmon to those fitting specific typings, often Ghost, Dark, Bug, Poison, and Fairy. This limitation encourages trainers to strategically assemble teams utilizing Pokmon that might not typically see use in the standard Great League environment.
Its value lies in promoting diverse team compositions and strategic thinking. It deviates from the standard meta, forcing players to adapt and innovate. The event often provides a fresh and engaging experience for participants, breaking up the monotony of the established Great League metagame. Furthermore, it allows players to showcase their skill and knowledge of lesser-used Pokmon and their matchups. Its occurrence usually aligns with a specific holiday period, adding a thematic element to the battles.
