Im not going to parse out the best or worst ones here, but they all kind of fit the description
6 Forbidden Light Forbidden Light is considered one of the best Pokemon sets ever conceived by some, so it's not really unbelievable that it would get a spot among the best in its own era
While a lot of the excitement of these games comes from building decks, fighting other players, and seeing if youve got the heart of the cards, there is another avenue of joy: unwrapping boosters
Shes sort of like Marnie (if you remember that card from the Sword and Shield era) and Roxanne combined only arguably more effective than either of them
Effect: When this card is activated: You can send one "Sora - The Keyblade Bearer" to the Graveyard, then reveal one "Drive" monster from your Extra Deck, banish monsters from your Main Deck the required monsters for its Summon, and if you do, Special Summon the revealed monster
To this end, the Ralts line is ideal for faster Energy production, as Gardevoirs power lets you use an extra Psychic Energy a turn, so getting it out quickly is ideal for boosting either Mew ex or Mewtwo ex
