Cloud is not only iconic, he's incredibly playable - as a mono-White equipment commander in his own right, or in the 99 of any Voltron or artifact-based deck
On the topic of things being dragged out, though, I will warn players that reaching all the goals can take quite a few plays as getting to those new cards as your deck grows isnt so easy
We Could Be Immortals, card number 219, is a Song card (appropriately, given that its the name of the Fall Out Boy song that plays over the end credits of the animated super hero movie, Big Hero 6)
A 2/2 Legendary creature Human Cleric with lifelink that costs two generic and one white mana, whenever you gain life you place a +1/+1 counter on Aerith Gainsborough
All those specific mechanics make FFTCG sound great, and as someone who has only ever dipped her toes in card games but never fully taken the dive, it makes me feel like this could be a more welcoming experience
