How does the Nemesis Beast gain Combat each turn, and when does its faction ability apply?

Accepted Answer

The Beast scraps the Trade Row card furthest from the deck, places it face down in front of itself, and gains Combat equal to the cards there. Its faction ability comes from the newly revealed card, applies after that Combat, and then the Beast attacks.
