Some cards, like source material cards and certain special guests, can be difficult to read due to having a transparent or no frame, creating a poor contrast. Not playing these cards isn't really an option, since many of them have no alternate printings and even if they do, it's not like you can force your opponent to use them. Having to play against several cards that are difficult to read isn't just annoying, but also represents a very avoidable accessability issue. I have actually lost a game, because I misread a source material card due to the lack of a frame.

I think that the ability to force the "View SImplified" option client-wide would be a clean and relatively elegant way to resolve these issues. There is already an option that hides alternate art styles, but it only works on cards where the art is actually tied to an card style. This addition would also allow players to have decks that are more aesthetically homogenous without having to skip out on any cards. I have personally not used cards that would fit a deck, purely because they stick out like a sore thumb

Alternatively (or rather additionaly) I would love if these types of cards would also receive alternate printings of them that have regular frames. Obviously that wouldn't fix the issue of the opponent having them, but it would still be helpful while making the game more customizable. A lot of iconic cards don't have their equally iconic art on the client.
