:) I have just started building decks of other (non-Deception) gods (and it helped to improve my Deception skills btw). I will think about including it in my Magic, never had this idea... Thank you.
War has a list of Guild units that can be combined with Diligent Architect and Desert Mercenary. I even invested in two weaklings with interesting skills from Genesis - Prodigious Armourer (at the end of the turn, give + health to a random) and Blacksmith Armourer (Roar: give +1/1 to each creature). However, War has so many powerful cards so maybe using Guild synergy won't seem useful for it.
