No, she discards it

“There’s no way I’m keeping THAT.”

“Too bad. I’m sure, the audience would like to get a glimpse of your body. Draw two new cards then.”

“Shrinking and Double Mental Drain. Oh no! NO WAY! You’re not turning me into a brainless bimbo. I want another draw” there was a hint of panic in her voice.

“Sorry, Karen, but such are the rules. You can only discard one transformation per round and you have to accept the new ones. Into The Chamber you go.”

Karen tried to fight fear as she entered the dreadful device. She even forgot about the five centimetres of height she was about to lose. Her precious intellect was at stake and there was nothing she could do about it. As The Chamber worked its magic or whatever it was it did the manager’s thoughts slowed down and thinned out. She was still worried and angry, but could not focus on either for too long.

“How do you feel about your new bimbo brain, Karen?”

“I… dunno. I don’t like it, I guess. I’d rather be smart again.”
