[2021] FYI Naru Meha + Double Major breaks Arena in an infinite combo, its impossible to decline out

We actually do have a fix for the loop detector to identify this style of situation and cause a draw now. It should come with AFR. The bug was that we didn't identify that spell copies might be mandatory, so the loop detector thought that the copies were being proactively cast (and that therefore something like running out of time would cause this loop to end, as the autoresponder would rather pass than cast anything). #wotc_staff
