You'll want to move as many characters to that location as possible , prioritizing characters with Reckless challengers, low Willpower questers like Simba, Scrappy Cub, and, if you can find her, Moana, Born Leader, who will ready all your other location-bound characters every time she quests
Youll want to be jamming with Yuna, Hope of Spira (just like the potential new best deck in Standard!), use Sanctum Weaver for big mana plays, and take advantage of the many enchantress card draw options, from Sythis, Harvests Hand to Enchantresss Presence
Which obviously has everyone scrambling to look up FF characters' birthdays, in anticipation of future spoilers
Julieta herself is a great target for Rapunzel's ability thanks to her four Willpower, so if you can challenge something with Julieta on turn four (using Mirabel's support again) you can immediately heal her with Rapunzel and draw even more cards
Final Fantasy games are full of loveable AND villainous characters and getting them in these decks was very important
