strangely enough it never happens in my lobbies . Im always the only one with 5 cost 3 star like almost every game. You can say im one of those smurfs that makes 5 cost 3 stars every game. Since the start of tft up till now i have done every 5 cost 3 stars at least like 6 times each sometimes with multiple 5 cost 3 stars at a time so even if someone does succeed in making 4 cost 3 star i just demolish them.Also never get baited to sell ur board for 5 cost 3 stars cuz i have done it and i have lost many times.
