As with anyone who doesn't understand footwork and positioning, castor swing all day err day. Or if by huddlecrab you mean some guy who rarely strikes back . . . if I remember how to play usually I just ignore them and attack someone else. You don't actually attack someone else. You pretend to attack some guy in front of you, who will block, which will free you up to attack the huddlecrab behind you, who thinks you're not paying attention.
