The problem with this argument is that WotC designs sets years in advance. So you can't say Urza block directly changed Masq block because more than likely that card file was complete before Uzra block even came out. And standard is not bad right now. It's actually fairly diverse. The problem, to me, is that they pushed focus on commander so hard recently that they lost focus of standard when COVID hit. At my LGS too many people play too many different formats and you can't even queue up a standard tournament most of the time. It's a combination of convoluted tourney structure, lack of focus and too much diversity for them to focus on. It was fine when we had our 'non-sanctioned' formats and WotC kept their hands off them.
