I'd like to comment on the grammar of 'Jazz Duelist's Challenge'. It should be 'duelists'' if the participants are duelists, and the competition belongs to them, and 'duelist's' if it's a Jazz Duelist who is hosting the competition. 'Duelist's' isn't incorrect because of this, however, because 'Jazz Duelist's Challenge' could also mean a challenge...for...Jazz Duelists. It is like 'Freud is the poor man's Jung', and 'we had mariner's pie for dinner'. It makes more sense when we add a definite article: 'The Jazz Duelist's Challenge'. Oh, and now we know why some people prefer double quotation marks.

EDIT: I wrote a comment about Sacrush's logo, but it turned out it has already been commented on, so it's gone now (I need new pronouns). Maybe they could fight over Eva, Fat Chick, or the Witch instead?
