Daily awards in girl events is a great step that increases competition for all players as well rewards (mainly for better players).
BUT do have overall ranking rewards as well - as for new starting player have to depend on this rewarded girls to get lower rarity girl cards that is equal to better players (common/rare/epic girls).
Please ADD some Gold (say 5000) and Gems (at least 50) as daily ranking reward - particularly at lower ranks (25 downwards), so that it is much more meaningful for new players to put in effort and get something actually more appealing (you can then have option to time reward with event goal 19 or 30).
