This is a bug I found a while back but I didn't submit the report, but here I am. It is a small bug and here is how to do it, it is for all consoles. Load into a game in any format, if you are on the play, mulligan and go to the icon where you can see the field of play and click your opponent's deck so it shows how many cards are in their deck and their sleeves, then wait until your opponent chooses to mulligan or keep and then the glitch will activate, you then choose whether to mulligan or keep, doesn't matter, the glitch will stay, you will always see the icon and be able to interact with it, the icon is the one from the start of them game, it only goes away once you are done with the match, I attempted to upload a video of how to remake it, but the file was too big so I'll leave it out since it is pretty easy to re-create. The workaround is to not look at your opponent's deck while in the starting screen and the expectation is that it shouldn't show the starting icon.
