i did realize "the tradition" from the ninja and then pirate event, but having another princess can't be any harm moreover i can't go all out because now i have only 13 sc, and from comment box of Lafate, more than 20 sc will be more promising
edit: yes i have all unit from the videos (stronger i can say) but thing won't go that smoothly, like you said harmless to try but don't expect to much
