I searched and I'm still confused.
Plot card gives me +4 gold. Location gives me +1 gold.
I have 5 gold in my gold pool.
Tywin gets 2 gold put on his character. So if I have a card that costs 7 gold, can I marshall it or does Tywins gold have to be spent on its own.
Also, the rules state choose a House card and an Agenda. In my base set, I have no Agenda cards. Normal, I presume?
Also, it would never make any sense to NOT defend a Military challenge right? Because if you're going to lose undefended or defended, you still have to kill a character.
