uh in english "may only" means that you cannot do it at any other point.

is status quo not english native by now? I mean loanwords are a thing.

@tttppp actually if you can "prove" a checkmate in x-moves a game is won. You don't have to play it out, displaying each and every move is enough. (You can't lose by time if you displayed it - given you still have to display it in regular game time).

The same could be said for modern sets like battle for zendikar. Yet those sets are often celebrated by the people from wotc.

@Rainbolt you don't do nothing, you make your calculations during those two hours. There's, exactly due to the limited information, a lot of fun non trivial equations about chance one has to solve before playing a card. I always find it annoying that halfway such a calculation a "judge" comes over and tells me I can't do that.

While I do understand the limitation of not being able to utilize a game clock - what I do not understand is why there is such aversion agianst games that take 2+ hours, with matches happening over the course of days/weeks. Even there some "guide" has to be employed for making sure one person doesn't take too much time. Yet we don't see this happening at all, and if I suggest it people just state "this is bad".
