Here's what I'm planning to run. Might cut the Bystials which would mean cutting all the lvl 10s. I've played the deck a lot and honestly never wished I had the second Blazar. If you're getting two level 12s out on field you probably won regardless, and Quasar helps push for OTKs since it doesn't banish itself.
Though admittedly most of the time I spent with the deck was pre-support and obviously you can easily put out double Blazar now with Primus, but Blazar+Supernova/Legatia/Quasar depending on the matchup seems fine to me.

I'd probably also rather have a second Primus for another backrow removal option over second Auxilla but I'm not crafting it just for this.
