thinking of several ways to spice things up.  
1. tag team death fight  3 in each side .  winning team is the one who are still standing . then the three to the death themselves   last one standing 
2.  boxing much to the death.  between two contestants ior maybe a series of matches perhaps a tag boxing  or kick boxing  
3.mum vs daughter fight anything goes on this  
4 fighting with swords or daggers to the death 
love to chat to anyone on this subjects
