I'm afraid of replying with this bag of yes's I collected from the back of my head. This would be so fucking awesome and righteous to people getting scammed. Sure, taking a screenshot is important when dueling. But should you be at fault and have a loss of items if you're getting scammed just because you missed out on a screenshot? Have a temporary screenshot folder that screens every outcome of a game if you wish to have this option on.

Also hosting ETouries would be more cool then :^)
