I think the issue is that, on the surface, players like the idea of "battlecruiser magic". If you do surveys and ask people what their favourite moments are, they'll tell you it's the times they slammed big spells against their opponent's big spells. Those definitely ARE memorable moments, but they're only fun when the format makes those moments special. It's like KFC. I love KFC now and then, but if I have it every day it becomes terrible. Well, Wizards is becoming KFC for its card game. It's giving people what they are saying they want; greasy delicious chicken.
But often, what people say they want and what they truly desire aren't the same. The reason people like "battlecruiser magic" moments is because they are intrinsically memorable. They are the cherry on top of the ice cream; the moment that said it was all over. But you can't get to that point unless there's a buildup to it. In my mind, Standard has just completely out-competed itself - there's no room for learning and experience because you just HAVE to play to pushed cards. And if you're constantly pushing cards to make sure you have control over the environment, you lose more control when those environments go wrong.
I think this is a good idea for trying to keep things status quo, but I think a shift needs to happen in terms of creating environments where you purposefully don't have complete control. Put in some cards that you know are good, but pepper the scene more with things that aren't good.
Felidar Guardian was a very interesting card because it broke the card in a way they didn't expect. Yet for as much as it dominated the environment alongside Saheeli, people constantly said that the play between the top two decks was incredible. Maybe I'm along in this, but if they made a few other "whoops" mistakes along the way, maybe there'd be a few more decks on top of that. Combo is an important part of the trifectra. You need some kind of combo to keep other decks honest.
I don't know... maybe I'm just rambling...
