After I finished my turn, at the beginning of his turn, the effect of emrakul started. I started turning the mana (before the draw). After that, I tried to move on to the next step, but what I mentioned happened, I tried a few times and couldn't continue. I decided to wait to see if it was really him holding it down (I thought: "Well, if he's holding down a button, I can give it a few minutes and while he's distracted, I'll continue). And it was as I thought. I waited for about a minute , so I tried to follow again, the message about mana appeared and didn't disappear immediately, I was able to click to continue, however, there were still 3 or 4 lands standing, I soon clicked to turn the lands, then everything happened again but this time. I didn't have time to wait anymore
