Let's take a quick look at what each deck does: Basri, Devoted Paladin Play a bunch of creatures and smother them in +1/+1 counters
Players loved her so much she got bigger appearances throughout the game's expansions, with one even being centered around her titled "A Shantotto Ascension." She's well regarded as an overwhelmingly powerful Black Mage and one of the most destructive allies in modern-day FFXI and is well known for speaking in rhymes, as depicted on her flavor text here
It would be a great gift for someone who already enjoys Lorcana
Even if you only have one, that would give Agrabah 5 Willpower and +1 Resist, meaning your opponent would need to commit a lot of resources to remove it
Then, when you're ready to win, just cast a Reshape the Earth to double her power ten times in a row and smash someone's face in with commander damage
We can probably expect that each individual deck will be an homage to the title those decks came from
