Not to say there's nothing here if you love flashy effects
Card draw is limited, so take advantage of it through cards like Kuzco, Wanted Llama and Cinderella, Knight in Training when you can
If you've already got a lot of cards from The First Chapter, apart from the guaranteed foils in the 2 decks, it might be more cost-effective to put your money towards boosters, unless you're looking to pick up the cards from either of the starter sets quickly, then the fixed nature of the decks will get you those quicker than randomized boosters
This suggests that some main characters or content from later Final Fantasy games, which might only be referenced lightly in the main set, could get dedicated cards in these special drops
Note: Passive and activated arent official terms, but mirror what other TCGs use
