@Neo Emolga Thank you for hosting the DBR2 game! It was a pleasure to watch it unfold (and report errors to you).

In addition to what you have already said : during the game, I felt like the Smart Cookie superpower wasn't really useful (due to the existence of the MacGyver + Cheaty Cookie combo).
Therefore, the following idea came to my mind : what if the Cheaty Cookie only lasted for one move instead of one battle (= when a player who has primed a Cheaty Cookie uses a move that is not very effective or not effective at all for the first time of the battle, that move becomes a regular or super effective move, and then the Cheaty Cookie disappears)? I'm not sure if that's a good idea, though.
(Something similar could also be done with the Brass Balls : when a player who has primed Brass Balls is hit by a super effective move for the first time of the battle, that move becomes a regular move, and then the Brass Balls disappear. I don't know whether the "+1 HP" effect of the Brass Balls should be kept or removed, though.)

Thanks again for hosting DBR2! :D

(Side note : in French-speaking countries, when a student points out a teacher's mistake, for example on the classroom's blackboard, the teacher often says that "they made the mistake on purpose to check whether the students were paying attention". Is that a thing in English-speaking countries? I assume it's not, since Neo never said that to me when I caught his errors during DBR2?)
