Idk, this is a complex subject and a great discussion.
There are a hundred ways to stop
Thassa's Oracle. The problem is, most decks probably aren't running a high enough interaction density to consistently interrupt it. But this can be said for any compact and consistent combo deck tbh. I have a friend who is annoyingly good at building these types of decks and I am pretty much forced to play my control deck against him everytime. It can be fun if all decks at the table have a similar amount of interaction or combo potential, but otherwise is downright torturous.
Personally, I am enjoying the current state of EDH overall. I tend to play at a higher power level and I enjoy tribal decks. I get excited when new cards get printed that fulfill a certain niche in my deck. The first card that comes to mind is
Spiteful Banditry. It's fulfilled an itch I've had for years where board wipes sit in my hand early game and ramp spells are bad draws late game. It's a fantastic card from a design point of view. It's usually a great draw at any point in the game. I bought as many copies as I had red decks, lmao.
Gameplay wise, yes some matches can be very fast but then again, I just played a nearly 2.5hr game where I was playing my best deck and other decks were relatively evently matched. It was fun. Lots of interaction and back and forth.
As far as power creep is concerned: if they printed a strictly better
Force of Will or
Cyclonic Rift I would be worried. VERY worried. But they haven't. They leave powerful cards alone and don't power creep to the point where I feel like rage quitting in the singles buying game. Some of the mobile games I've played have shown me just how bad power creep can get for the sake of $$$ and magic is nowhere near that tipping point.
They've been introducing new archetypes like "clue tribal" for example and I think that's a great thing for the diversity of the game, while adding support for existing archetypes.
At the end of the day, I'm still having fun and feel good about buying singles and building new decks.
