The Starter Kit has Cloud and Sephiroth up front and, considering this will likely be a first foray into MTG for a lot of Final Fantasy fans whose interest has been piqued by the crossover, is a perfect place to start
The main view contains most of the core code, including the filters and page navigation header, with the logic for rendering cards broken out as a component
Its interesting to note that if you want to make the card get more incidental value, some versions of cards from the Portal sets have reminder text, like the Portal 2 version of Ravenous Rats (although I dont think that has a home, even in pauper cubes)
The two most exciting are Dorothea, Vengeful Victim and Katilda, Dawnhart Martyr
However, at the same time, a mysterious entity, called Astral, appears before Yuma, and tells him to "stand up and win"
