You always walk the edge of a knife with Spiderman, too little praise and we don't get his good ideas and effort, too much and he begins to forget that with great power, comes great responsibility.
Actually, I initially championed Braids, because I felt that the effect was powerful but not overly so, and increased player decision making. But I didn't really have a strong attachment to any of the cards, and some I was against. So basically the fact that it was a classic sort of multi-player card (cheap to cast, but big effect when multiplied over multiple players) carried the day.
