In the Duelist Kingdom tournament, Bonz, Sid and Zygor met Bandit Keith, who agreed to coach them through the tournament, so all four of them would advance to Pegasus Castle. Keith wanted revenge against Maximillion Pegasus for humiliating him in the final match of the Intercontinental Championship. While helping them win Duels the first day of the tournament, Keith secretly intends to use them for their Star Chips. When Keith finds out about Yugi Muto, Joey Wheeler, and the rest of the gang, he plans to get in their way and eliminate them.
You are right here. The Rematch string is part of the Info box, and as such it should be parsed correctly. (The string that contains the correct and breed/damage-specific min health requirements). This should be enough, but, I think there are also folks that aren’t using Rematch. They also should know of the type-specific min health requirements. Unfortunatly the default forms of the page don’t offer any detailed entries for the min health. They only offer one entry (for all damage types), and I always put the worst-case min health there (for pets that are weak against the expected damage type)
