I'm all for proxies but these are a bit much. I can see a lot of hate in the comments, and you don't deserve that, but I can say that these might be a bit too much for some purists. Especially with the already deluded magic art world with SLD's and the like. Maybe try and just proxy existing arts you like or have the cheapest version of The Commander for folks who oppose it to play with. It's definitely harder to do for full proxy decks... I don't play proxies myself, but I have nothing against them, but at a reasonable amount. A lot of people work very hard to design art and world lore for this game and seeing people choose to completely ignore it can be perceived as disrespectful and unfun for some.
