@thewhitedragon69 Three things to think about in response to that.
First, power creep in general is not a great thing for the game. It's a short-term boost in sales, sure, but it's long-term detrimental because you either have to fall back and print a Masques or Kamigawa and deal with disapointed players and disappointing sales or you keep on creeping and things get more and more unbalanced. They've tried to balance this in the past with power creeping different aspects to different sets at different rates, but that seems to have been thrown out the window recently. It's very legitimate for people to worry about what sustained power creep means for long term health of the game.
Second, perhaps by accident, WotC's recent power creep may have come at the exact perfect time to actually be the right call. With Covid shutting down paper magic hard, Arena is probably picking up steam. All the recent power-creep sets are on Arena, and having splashy, powerful cards on that platform is good for that game. I don't play Standard typically, and I like the meta on Arena right now in standard. It's powerful and flashy. Feels more like eternal, complete with combo decks, than it has in a long time. If you were going to choose a period of time to mortgage paper magic's future in exchange for a boost online, now seems like exactly the time to do it.
Third, overall, I think this power creep + ban trend is good for eternal because it means they're finally shaking off the chains restraining them from printing cards as powerful as the old hard-to-obtain cards. I've been a big advocate for helping people get into eternal by printing cards that compete with the old reserved list staples, and they're doing that. I don't think they've gone far enough into making the new cards MUTUALLY EXCLUSIVE with Vintage staples yet, but they're certainly making sure that the Vintage metagame is chock full of new and relatively cheap cards at competitive levels. That's a good thing! But, of course, since Vintage is the Whos-Who list of Magic's Greatest Mistakes, when you print cards to compete at that level you are absolutely going to have to police the format against breaking.
Its funny that you wrote this (and I have always agreed with this as it actually empowers newer players to engage in older formats). There was a recent poll on twitter by Mark Rosewater and it split the length of Magic's existence into 4 portions, my favourite was the oldest and the newest
