MTG standard was better 25 years ago when every other creature didn't have all these overpowered abilities and there was a lot less overpowered combo. Combo tended to be accidental as well and discovered by players. MTG used to be more fun. Now whenever I run into any of these tier 1 decks, the game becomes unfun because they're all gamebreaking combo decks.

Gruul Aggro? It's combo with cards designed to run that way. It's practically a WotC designed deck at this point. All the cards the deck what it is should be banned. This deck is also an example of WotC consistently giving White, Green, and Red too many overpowered cards. Black at least has true drawbacks to its overpowered cards

Self-Bounce? Uses all the cards that should never been printed like Stormchasers talent. Graveyard play in the large quantities it has been at least since Inistrad was always a mistake and printing one card counters to it does not fix the problem. It's still there.

Domain Overlords? Overlords should never have been printed. Moreover the failure to adjust the rule set for the impending cost allows Up the Beanstalk to be even more overpowered than it already is. Not only that, it's an example of WotC given white, green, and red too many overpowered cards. Domain and impending itself is a bad idea like every form of mana cost reduction ability especially when cards based on mana cost are still triggered. They were mistakes when it was affinity for artifacts breaking standard. It's still a mistake now.

Tier 2 decks don't fair much better as they're just less used variations on the Tier 1 decks or run their own overpowered combos with self-comboing cards like Unholy Annex/Ritual Chamber or the excess of overpowered cards that have triggers based on lifegain or lifeloss.

What WotC needs to do is to slow the release cycle for new sets back to once every 4-5 months. Thoroughly playtest the game with ALL the sets in standard to make sure there are no overpowered combos such as what is currently making up standard. Second WotC needs to reduce the amount of sets in standard back to 4-6 sets in total spanning at most 2 blocks.

Third foundations needs to go out of standard sooner than 2029. It really should be removed from standard in 2026 or sooner while being replaced with a much more balanced set that attempts to the same thing without all the combos and overpowered cards that were introduced in foundations.
