Even before the neutral cards for Bastion Rising were spoiled I had this deck because I've seen that we now have enough neutral cards to make decks be dual "faction" with factionless. I figured I'd post this deck as a sort of prototype for others to use as these new colorless cards come out such as the one that prevents summon effects or Celebration (which works great with Tempting Offer). I've had good success with this in Throne as is depending on the meta and hope you and others can make more variations of this with other factions! Best of luck and have fun!
Note, the faction breakdown doesn't show this, but it is 40% Factionless. Also, turn 4 attacking with 2 7/7 golems has been a reality.
