Childe of the Revolution is the only new libary card in the upcoming New Blood (2023) expansion. The card is mixture of the existing cards Embrace and Third Traditon: Progeny/Creation Rites, in the sense that Childe of the Revolution must hunt the turn it enters play (like Embrace), and requires a titled vampire and you can search for Discipline card (like Third Tradition: Progeny/Creation Rites). It will enable a lot of Anarch swarm decks using Consanguineous Boon for bloat, and of course, Revolutionary Council for the kill.
I like about the card (beside the artwork), that it has this little variation between Embrace and Progeny. On the other hand, if you want to build a deck around it, then you need 8-12 copies of the card. So you either need to buy 4-6 New Blood: Brujah decks or trade/buy these cards, which will be difficult initially. I would have preferred maybe 3 copies in each deck (instead of 2).
