Building before painting. At least that’s how I’m doing it, to a point, then I’m going to have to paint some subassemblies before the final gluing.
My own house lance, house Aegyptus and two free blades. The Green Knight and The Black Prince. Going to go with fewer magnets than I had originally planned, but still magnetizing being so close to 11th edition and not knowing what it will bring, flexibility.
