It's a bit of a hobby of mine to make, copy, edit, or otherwise think about character decks. Character decks which fit not only the original character's personality and playstyle, but also the vibe, be it the visual aesthetic of the cards, or how well their effects synergize. The typical philosophy is this; only run singles of each card unless you require multiple copies for a particular strategy, use as many cards that character actually used themselves (or a good substitute if the card doesn't exist in the actual game), maintain as much of the original vision, playstyle, and personality as possible, and beyond that just have fun. You're not limited in era so you can run as many retrains or modern support for the pre-existing cards as you want. But that's anime characters, this deck is my own personal character deck, which hopefully encapsulates me as much as possible, it's not meant to be competitive or even particularly good, just something I brainstormed one night while bored and winding down for bed.
