I'm not sure I agree with their assessment of Standard, but I think what bothers me the most about it is the explosive powercreep in it over the past few years. Current day standard feels a lot like old (pre-MH1) modern, and I guess that was a fun format as well, but it's so high power compared to what standard used to be. There are some cards that contribute a lot to the explosiveness (Monsterous Rage for example), but every card that sees play these days does so many things that it's not even comparable to old standard anymore.
I guess I just wish we could have a lower power format again. It's wild to think today that Divide by Zero got banned in standard just a few years ago.
