I haven't played Standard since... RTR-Theros I think? As someone who only marginally plays cardboard Magic (can't even qualify for WMCQs lol), a format that rotates within a year and cards get worthless in an instant is deadly. I learned my mistake. Never buy into Standard.
I feel like there needs to be an in-between for Standard and Modern, but the key is that unlike Extended, there should be a reasonable expectation that you don't have to upgrade your deck. You should be able to just bring your Theros standard deck and have a reasonable chance at winning.
Perhaps they could start doing "Standard vs. Standard" events in the month before a new set comes out. You can bring decks for the current Standard, or a deck from an old Standard that changes every week, with no card crossover. Or perhaps you can mix and match, but you start with one less card in hand. You register with the Standard you will be using, and it will be a casual event, so you don't have to list your entire deck. In matches, players will be required to say what Standard they are playing with, and if someone notices or suspects they aren't sticking to that, then a judge can be called over.
So one week could be Theros vs. Kaladesh, which is to say, (Return to Ravnica block + M13? + Theros block) vs. (Battle for Zendikar block + Shadows over Innistrad block + Kaladesh block). Then the next could be Innistrad vs. Kaladesh, and so on.
This would be easier to enforce online, but if the judges encourage players to ask them if they suspect a card isn't in the format, and the judges actually know, then it could work out in paper.
