Fairness: Prevents "marked cards" in competitive play
TheChirurgeon: The other half of the Vastra-Flint duo, I like her synergy with her partner using the clue and food tokens, and those are also a nice touch and a good nod to her working as a detective with Scotland Yard (and potentially being the in-universe inspiration for Sherlock Holmes)
This one features a Mega Rayquaza that has a golden rule box and golden borders
Doubling Season works exceptionally well here, doubling both the number of counters Goldvein Hydra enters play with and the number of Treasure tokens you get when it dies
Since Psychic Pokmon were already so ubiquitous and versatile, turning other Pokmon into borderline Psychic-type cards instead of Fairy-type cards only bolsters their ranks
Sword and Shield boast a much more open-world structure than previous Pokmon video games, allowing you a lot more freedom and a chance to truly play the games to your own beat
