I'm not sure how "evil" it is really. Sure it's annoying as hell, and unless you had a camera it really comes down to whoever is more persistent. We'll have to give the previous queen the benefit of doubt that when she argues that it's her win, it is (weird as that may sound). Karuta is, after all, about whoever touches the card first - not who removes it from the field.

As for intimidating, that's what aggressive karuta that Dr Harata teaches is all about anyway.
