Need help with artifacts for team

I am building a Flins team but sadly am Ineffaless. The comp is Flins, Columbina, Fisch and Sucrose and part of me is stuck on using Aubade of Morningstar and Moon for Columbina, but knowing that Silken Moon's Serenade is also really great I am not sure where to slot this into, so just hoping for some advice on what might be the best play here (running Bina with Serenade instead of Aubade, or giving Serenade to one of the 4 stars?)
