Today I'm going to talk about everything I'd change about Magic if it were all up to me. The title is intended to highlight the level of fantasy involved in this exercise as well as a self-aware level of childishness and naivete about some of these changes; while I'll acknowledge practical concerns, there may be a lot of points that aren't realistic or that too many others wouldn't like. While some ideas might be a bit pie-in-the-sky, I intend for this to offer serious ideas that I think are worthy of real consideration as well. Let's start with the easiest changes to implement:
Changes to the Banned and Restricted Lists
Paradoxical Outcome is a card I expect WotC will restrict fairly soon. It's basically a better version of cards like Windfall that are already on the restricted list in this format, and there's no real reason for it to remain legal as far as I can tell.
I'd want to carefully monitor all the cards being unrestricted here, but I think it's unreasonable to restrict four different artifacts that are fine in Legacy just because Mishra's Workshop, a card more powerful than the vast majority of the restricted list, has immunity because it's worth a lot of money while leaving Shops as the best deck. I think Vintage would still see Mishra's Workshop + artifacts as a defining strategy even if Mishra's Workshop were restricted. Bazaar of Baghdad is another card that simply isn't reasonable on power level and weirdly has immunity.
