Thanks for the feedback! The only problem with Thunder/Lightning and Magic/Wizards is that they don't actually fit into a category, they're just pairs. For example, if I were to include Thunder/Lightning, then the clue would have to be something like "Weather," in which case I'd have to add Heat, Hurricanes, Suns, etc.
I don't understand your "real people" category. Is it proper names? Vikings, Patriots, Senators, Redskins, Trailblazers and many more are "real people".
Magic & Wizards?
Mavericks and Warriors?
What is this quiz based off of?
That last comment was just offering more pairs if you wanted to add on (Thunder/Lightning, Magic/Wizards, etc.)
