Did we get any of these things? From the discourse (even here!) there seems to be even more eye-rolling going on around un-cards. Aesthetically, I do prefer the acorn holostamp to the silver border, and I think complaints are overblown about how easy it is to differentiate legality - certainly it's more straightforward than showing a player the 10 latest booster packs and asking them to know whether the contents are legal in Standard, Modern, and/or Legacy - but I do not think we saw the interesting, bizarre, or wacky cards at the same volume of previous un-sets that would've made this aesthetic improvement meaningful.
Overall, not as fun or interesting as previous un-sets, and if these had the silver borders, I'd be running a whole 0 of them for aesthetic preference reasons. But hey, we've gotten plenty of good sets already this year. Let's go Secret Lair 40k and Brother's War spoilers
I think this is actually the best Un-set, by virtue of the fact that it is actually trying to be a cohesive Magic set. Allowing some of the cards in this set to be eternal legal meant that the designers had more freedom in what they could feasibly put into the set, since in previous un-sets only cards which couldn't be done in tournament legal magic were allowed (with some very minor exceptions). I think previous un-sets were hurt by the fact that everything had to be so mechanically outlandish to the point that they don't mesh well with non-un cards. This set, by contrast, uses its acorn cards to make cool designs that make intuitive sense but couldn't work under the normal system without a comprehensive rules re-work. Cards like
Nearby Planet,
Far Out, and
Killer Cosplay all look like really fun cards to Cube with, and they probably wouldn't exist if the set was forced to be as weird as possible. I think Unstable was hurt by the fact that a card couldn't be "normal" unless it referenced contraptions or the host/augment mechanic, and cards otherwise had to have some weird rider attached to make sure they were purposefully given some element to make them unprintable.
As for the lore complaints and eye-rolling, I think people are just getting sick of the Magic product release rate. WOTC is getting to the point now where they're making a ton of products that
could appeal to everyone but in reality, only appeal to a subset of the player base. It's not like back when I first started playing when every product, including the supplemental products,
had plants for people who might otherwise be uninterested in what they were producing. However, I think sometime around 2017 or 18, WOTC realized that they could make products
only for people who play certain formats or have specific interests in mind. That's around the time when we stopped seeing cards specifically planted for eternal play in Commander decks and when we started to see the early prototypes for
secret lairs and
universes beyond. However, I think so many of us had become accustomed to everything trying to be for everyone, that we all still treated these products as having relevant stuff that should be for us. Flash forwards to now, when we're getting new cards basically every month or so, and I think it becomes hard to follow.
Unfinity specifically is getting the short end of the stick here. The set wasn't originally supposed to be a "black border un-set." It only morphed into that near the end of the design process because Adventures in the Forgotten Realms brought dice rolling into black border. Since a huge portion of the set basically already worked in the normal Magic rules, the decision was made to make those parts of the set eternal legal. While this move had the benefit of preventing EDH players from rule 0 bullying people out of playing otherwise harmless un-cards in their decks, it had the knock-on effect of making a bunch of these cards theoretically relevant in constructed. However, the set is still quintessentially Un, despite the fact that it's designed more like a high-concept normal set than previous un-releases. As a result, I think a lot of people are seeing these legacy-legal Un-cards and thinking "wow, this seems forced," when the reality is that these cards were never meant to be competitive staples.
Basically, a set that wasn't actually meant for a legacy is being viewed as one, which is creating disappointment. This is not helped by the fact that these cards are being previewed days after the controversial Warhammer set.
Honestly, I'm past the point of caring what other people think about the constant releases and broadened lore. People are going to complain about good sets no matter what, and by internalizing those unjust grievances, I'm only making myself miserable. I mean, people complained about Neon Dynasty for Pete's sake and that's one of the top 5 best standard-legal sets of all time. Magic players just like complaining and the only way to be happy is to tune it out.
