Royal Family looks meh to me. Essentially it reads "if you take 3 GK, you pay 10 points for an artifact and +1 on Courtiers' returning abilities". Looks like a good deal except you now have massively redundant spellcasting and summoning on an otherwise unimpressive model. Unless you're using realm spells, you'll be forced to cast shield / bolt with two of these guys, and are you really using 3 rounds' worth of command points on Man-at-Arms? Probably only if you're not even fielding a GKoTG/GKoZD.
