How about:
Heart Cutting Savages?..................Has a nice ring to it!................
At least “Aztecs” has a warrior-group/fighting connotation. What gets me are these teams that name themselves “The Force”, “The Heat”, “The Magic”, or some other abstraction. It doesn’t even have to be a fighting name to be legit as long as it is a name that denotes a collection of individuals...like Cornhuskers, Steelers, or Golden Gophers. But names like “Atlanta United” or “Stanford Cardinal”...lame.
