Not amazing, not dreadful like some others.
Perhaps a 4/10 overall? This wasn't really terrible like many others and I would give lots of 1-1.5's on others. 9-9.5 for amazing. And I guess you are stuck with a 4 then.
Also really, really, small nit pick. In turn 7 you refer to Celebii as female. I know that it can be argued but I didn't like it. (This has nothing to do with my rate just something very small I don't like).
Green Mage- Surprise factor requires the surprise to be effective in order to be a valid strategy. If I planned on throwing cottonballs at your face, I wouldn't need to sneak up on you to do it; you'd just take a few cottonballs to the dome and proceed to beat me up. There would be no reason to have your guard up while i'm threatening you with cottonballs. Offensive whimsicott is that cottonball.
