Put simply the "Hide Alternate Art" setting doesn't work. When I enable it, as soon as I leave the Gameplay settings screen, the option is disabled again.

Further to this, this settings does not help with the readability of cards that have alternate printings rather than alternate art. The Final Fantasy bonus sheet cards are a prime example where the cards not only have alternate names, but the templating makes it almost impossible to actually read what the card actually is. There needs to be an "Always Show Simplified Version" options, and further to this, every single card without exception needs a simplified version programmed onto the client. It's extremely poor from an accessibility perspective not to have these options in client. People with visual and cognitive processing impairments struggle hugely with issues like this.
