2022-10-07 : Art Appreciation doesn’t target the nonland permanent. You choose which one is getting the sticker as the spell resolves.

2022-10-07 : If you don’t put an art sticker on the permanent because you don’t have any available, the outside person should rate the card’s existing art. Perhaps they should dock you a point or two for your lack of originality. Who are we to say?

2022-10-07 : The outside person is rating the new art, considering the way the sticker synthesizes with the original art. Does it produce a harmonious aesthetic? Does it make a worthwhile commentary on society? Does it present a fresh viewpoint in a landscape rife with imitation and vapid regurgitation? Or, if they must . . . is the sound effect funny? Sigh.
