Heirs to the Blood

New expansion will contain 170 new cards.
Most important matter that remains is if there will be reprints in this expansion. Last few expansion was made either of some reprints and some new cards or only new cards. New card only expansions had 60 or 150 new cards so I hope that HttB will be similar to KoT and 3rd edition rather expanded 150 card version.

Edit: It was only rumours that there will be any cards available only in starters.
