remix and fight the next oppent.. each characters get 3 chances currently... might be changed later on. if other people are out of lives then you can revive them by giving them 3 moer.... but you can only give them 3 ONCE and you cant give them to anyone else after your pick... so use wisely.... but you can give 1 life to 3 different people... you can only give out 3 lives in total!
