GO Battle League: Twilight Trails

The Twilight Trails season of the GO Battle League runs from 8 September to 1 December, with ranks reset at the start. Mega-Evolved Pokémon can now battle in the league through Mega Edition versions of the Great, Ultra and Master Leagues and several Mega-themed cups, and many attacks have been rebalanced or added to Pokémon's movesets. Climbing the ranks earns Ryme-inspired avatar items and reward encounters, and a free Timed Research pass tracks your wins all season.
