it's to have formats that are resilient to being solved

Oh, is that all they have to do? I wonder why no one at Wizards had the brilliant idea to just make better formats with more balanced cards?

This suggestion is up there with stuff like "Why not just program the AI to play better" in video games.

It turns out, this shit is hard. This is a company that literally invented the genre, and has been doing this for more than 20 years, and they've had dominant decks rise to the top.

Yeah, there are things they can do a better job of (like the QA/playtesting that missed Copy-Cat), but we've also been told recently about changes they've been making to try to address some of these issues.

Don't get me wrong, I don't think that even further reducing the number of MTGO decks reported is any kind of a reasonable move, but it's basically a tautology to say "the trick to keeping Standard from getting stale is to make a better Standard that can't get stale" as though the goal this whole time has been for them to try to make environments that are solved and stale within weeks.
