Master Ball Tier and Champion Tier are the highest possible ranks in Pokémon Champions.
These ranks are only available to the best players in a given season, and not only are they reserved for the best of the best, but they are initially unavailable when a new season rolls out.
This guide explains when Champion Tier and Master Ball Tier fully unlock in Pokémon Champions.
When do Master Ball Tier and Champion Tier ranks unlock each season?
Master Ball Tier ranks 1-3 and Champion Tier in Pokémon Champions take one week to unlock after the start of a new season.
In the case of Pokémon Champions Season M-7, that's Wednesday, 14th October at the following times:
- BST (UK): 3am (Wednesday, 14th)
- CEST (Western Europe): 4am (Wednesday, 14th)
- EDT (East Coast Americas): 10pm (Tuesday, 13th)
- PDT (West Coast Americas): 7pm (Tuesday, 13th)
For those at Master Ball Tier rank 4, you're then able to climb the ranks all the way to Champion Tier. Good luck! Hope you get the rank you're aiming for before the next season starts...
