Every character appearing on those cards has got some dominaiting element: snakes, skeletons, Samurai X (and it's not Ice, but Fire and Lightning). That doesn't mean every character has got some power. And back then, it would be strange if some villain kid would have perfectly balanced stats.

They have got some influence from LEGO, but from some management rather than scripting team. Tommy Andreasen wrote he wasn't involved in making some shorts, like "Wu's Teas", so why would he be responsible for some cards? And if you really need any explanation, just assume that's his fauvorite element.
