The standard/official design for field center cards bothers me a bit. I think it's because the design favors one player over the other. When a field center card is on the field, it's layout, artwork, and text all face one player leaving the other to view it upside down, plus it looks too much like other cards on the field.
So being the meticulous and pretentious snob that I am, I decided to redesign the field center card to better suit its purpose in two ways:
The main design is symmetric so both players see the same, or at least, a similar view rather than one having to see it upside down.
It's more of a plate than a card so it sits in the field center as a solid stationary object rather than a flimsy card which can easily move, as well as giving a pseudo-rectangular border to further distinguish itself.
I've included several designs; some are based on the standard design with classic Yugioh artwork and motifs, and others I've taken an out-of-the-box approach to see what I could come up with. Surprisingly I've only seen two other people make a field center card with a symmetric design: https://imgur.com/oZIEghK & https://imgur.com/a/JQwu8
