If I attack with Former Champion and it has no power on it, but then claims a power from renown (after winning), does it acquire deadly during that same challenge? (In other words, if renown is checked before deadly, it seems like Former Champion would acquire deadly during the first challenge it wins, rather than after.)
The practical question for this is does my opponent's character die to deadly (assuming he doesn't choose to kill one of the blocking/participating characters) if I swing with a 5 STR champion and he loses?
