Since the Final Fantasy decks are pretty new, anyone who hasn't been testing them ahead of time online through unofficial channels like Tabletop Simulator or Cockatrice likely hasn't gotten a good idea of how well each deck plays just yet
That means, to get all three, you must play in both days of the Casual Play, and then also take part in the Willpower League
New additions like Miss Bianca Unwavering Agent give the game better reach to control the board outside of singing songs
Please be aware, I have not personally tried or tested these , but going by their reviews, they seem like solid choices
And the last two sets released truly are the epitome of this, with a clearly unpolished and perhaps straight-up bad set ( Spider-Man ) leading to a vibrant and exciting product filled with new and interesting mechanics ( Avatar )
Oloro, Ageless Ascetic is the classic high-power pick (passive value from the command zone, three colors of payoffs)
