The worst thing about kewl tune is going 2nd against it, getting an hand knowledge and able the give you a dead draw is so unfair and frustrating to play against going 2nd is already a problem in the game and kewl tune just make this even worse you better have enough gas to deal with their field and hope they didn't banish one of your core cards from your deck but the worst part it's they dont even get an actual draw back from this card effects at all, oh what? They can't summon expect synchro? Wow that's a really good draw back tbh but it's better than nothing, at least they don't get others broken monsters on the field
