That works. Most Player characters would get two matches and the two finalist would get a playoff in the third round.
Also it looks like not everyone can fight an NPC the first round so unless Scar wanted to show both of his characters battling I'll volunteer to duel someone else in round 1.
Our Gm is away right now but i'm fairly certain he wouldn't mind another person joining so it would probally be okay to whip up a CS and wait from him come back and approve.
Since we are all writing out our own duels then I think its fair for the tournament line up to be decided by order we make our posts and write up our duels.
Sorry for lack of activity my gf just gave birth to our second child the other day so I've been spending time with them I'll have a post up by the end of the day
