PlaceholderAPI Placeholders

%uppercut_puncher% : who last punched you
%uppercut_puncher_{placeholder}% : who last punched you, with placeholder relative to them
%uppercut_target% : who you last punched
%uppercut_target_{placeholder}% : who you last punched, with placeholder relative to them

Obviously, %placeholderapi_placeholders% will not work in the messages unless PlaceholderAPI is installed. Using relative placeholders (eg:%uppercut_target_player_world%) also requires the expansion for the placeholder.
