When it says "cards you control" does that mean Plot cards as well? Or do you not "control" Plot cards? What about Character cards that give themselves gold that you are allowed to use?

The plot card doesn't provide a "gold bonus" (eg +1, -1), but rather just your base income .

See core rules for "Income Bonuses", and the core rules describing the "gold" icon on your plot (income, not a gold bonus).


Essentially, while the Searoad becomes useless, neither your plot card nor your Tywin Lannister (Core) is affected by KotHH.

Tywin isn't affected, but Lannisport Stewards, Councillors and Weaponsmiths would be, as would CS Littlefinger.

And unless I'm mistaken, it makes you immune to the gold penalty of Burned and Pillaged, as technically it counts as a "bonus."

Yup, that's right (hence me specifying under "gold bonus" in previous post).

Does it make you immune to the Gold bonus of Master of Coin in Melee, as well?

The Title is not a card (even if represented by a card). Ergo, it is not affected by KotHH.

EDIT: Never mind, I already found the answer to the question I had asked.
