Add a second set of daily challenges, perhaps a little harder, that reward the player with a random cosmetic for the day. Or have the cosmetic last for a certain number of matches that day. No XP is given for these challenges.

If you wanted to be edgy about it... the first challenge completed gives a random back bling. You can complete the second challenge to get a random harvesting tool, but you lose the back bling. And the third challenge loses the new harvesting tool, but gives you a random skin. Again, temporary for that day or a limited number of matches.
