Cynthia & Caitlin is good because it recycles Supporter cards (generally the best kinds of cards in the game), and its discard effect lets you still go plus 2 in card advantage (and go even if you don't use it)
And finally, because Farfetch'd is a "colorless" card, it can be included in any deck and can use any type of energy, so it's very versatile
Munkidori has been doing very well competitively, and this beautifully rendered card is likely going to find its way into one of the many decks that run this version of the card already
The booth will also be selling card sleeves with official Final Fantasy artwork on them, that will hit retail shops later this year
Elsha of the Infinite I mean, it says it in the name, right
I highly suggest giving the game a try for yourself if you haven't already
