In The First Chapter, Enchanted Rare cards could be found in roughly 1 in every 72 booster packs
So far, this rule has made perfect sense, as the existing Meld pairs have worked around this ruling
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
Which obviously has everyone scrambling to look up FF characters' birthdays, in anticipation of future spoilers
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
