This is the kind of thing that could see play in a Legacy Elves deck
They are all strong causal cards in addition to being tournament playable
That means they are all reprints of existing cards reskinned with concept art and characters from different Final Fantasy games - so while there are no brand new or mechanically unique cards here like the ones that have been shown off recently or those in the Commander decks we previously revealed, they do have art that stretches back all the way to the very first game in the series

Clues and Treasures are generally meant to be used for their own abilities (drawing a card or generating mana) rather than Food and Blood (which could be spent by many cards in lieu of generating food or rummaging)
Form of the Approach of the Second Sun works in a way similar to Form of the Dragon, except this time you turn yourself into a card and get shuffled into your own library, forcing you to balance some cards on top of your head
