Kanto Stadium
Welcome to Kanto Stadium! This is a collection of formats inspired by the official competitive ruleset (Nintendo Cup) as well as the 4 cups introduced with Pokémon Yellow (Prime Cup, Poké Cup, Pika Cup, Petit Cup).
These formats are the preferred way of playing Gen 1 in Japan, and the Bring6Pick3 ruleset has always been the standard for official tournaments. It offers a more 'authentic' Gen 1 experience, where the metagame is more flexible, but individual games are more volatile.
Rules
- Standard RBY Mechanics (not Stadium)
- Team Preview
- Bring 3 out of 6
- Species Clause, Sleep Clause, Self-KO Clause
- Prime Cup: any level, all Pokemon allowed
- Poké Cup: level 50-55 (155 max per game), Mewtwo & Mew banned
- Pika Cup: level 15-20 (50 max per game), Mewtwo & Mew banned
- Petit Cup: level 25-30 (80 max per game), must be unevolved, max 2m height 20kg weight

History
These formats were played competitively in 1999 for the Pokémon League Training Tour, the first series of tournaments to take place outside of Japan, spanning 26 American cities. They featured Prime Cup, Poké Cup & Pika Cup, and were played using Red & Blue. The rules are the exact same, although they did manually enforce Freeze Clause. Also, most players nowadays prefer to play with Evasion moves banned.
