The Rainbow Cup Rules
The Rainbow Cup has a few special rules (designed to provide added challenge and fun) that differ from standard PvP combat in Pokemon GO:
Competitors will bring a team of 6 Pokemon (and register them before the tournament begins). All battle parties used must be comprised of these 6 Pokemon.
Matches are played in Great League: only Pokemon up to 1500 CP are permitted in the Cup.
Only Pokemon with at least one of the following types are permitted: Fire, Electric, Bug, Grass, and Water.
Only Pokemon from the 1st and 2nd generation (Kanto and Johto) are permitted. (No Alolan forms!)
Legendaries and Mythicals from Gen I and Gen II are permitted. There are no single-species bans in Rainbow Cup.
Only one of each Pokemon species is permitted on your team of 6. (No species duplicates!)
Arena Rules will be followed in all other particulars.
Take a moment to review the Arena Rules linked above - particularly clarifications in regards to technical difficulties and an optional coin toss to determine which opponent sends battle invites, due to a suspected ordering advantage.
