Whenever Bill comes up with a mechanic (or card or theme), he sends me an email
The main set has 204 numbered cards, with 18 Enchanted alternate arts numbered over 204
Princess Power perfectly sums up the Amber/Sapphire deck, full of royalty like the foils Ariel Singing Mermaid and Mulan Considerate Diplomat
These are both pretty expensive cards, but they also very clearly "build arounds." I'm a big fan of Roon of the Hidden Realm because I love being able to blink cards with "enters the battlefield" abilities, and Y'shtola is not only able to blink twice every turn, but she also doubles any other "end of turn" effects that trigger as well
The only issue with this deck is that it doesnt have a ton of cards that are still competitively viable today (with a few notable exceptions like Lefou Instigator and Shield of Virtue)
Lastly, there is a Chocobo-themed box with plenty of goodies for fans of either game
