One would say that certain matchups are famous, like orc vs human, orc vs wood elf, or skaven vs dark elf.
Other would say that other matchups are interesting, like halfling vas ogre, or vampire vs goblin.
But few people would deny that amazons suck vs dwarf and chaos dwarf.
Whatever led me to play amazons vs chaos dwarf - a little piece of stupiditiy, a sense of madness, a portion of recklessness, the ethic to play with the team with the closest possible TV, and the need of mental challange - , it was huge fun at the end. My 7 sisters defeated the Chaotic 7s abusing the lack of rerolls on the opponents side, and using every bit of luck in the process. Great efffort from the ladies, they never really feared the mighty tackle, and bravely stayed between the ball and the closest dwarf.
This victory is a statement that everything is possible in blood bowl sevens. If you have never heard about this rerolless league with flashy games, then i suggest you to visit the bb7s chatroom in IRC, or check the group page at:

I am more than happy to share the excitement with you!
