Yeah, those work. Everyone can get as creative as they want; Risus makes it happen!
However, Subatomic Shrinker and Strong From Her Size would be inappropriate cliches for this combat, since those don't really fit with verbal arguments. I mean, they could (any cliche could, if you really stretch your imagination), but I have to make a determination somehow.
You can still use them, of course. Hint: Risus wants you to use inappropriate cliches. You can delete 3 dice without a serious drawback? Badda-bing!
Sunshine and Rainbows could go either way, I think, since it refers to both your personality and your "solar flare" ability. Right? Or is it one or the other?
