So this would not work during plot phase because you have no gold yet and there is no plot phase action window until after "when revealed" effects have resolved in initiative order... Am wondering if you must be the first player to negate a plot when revealed effect in order for this action to resolve first? Seems very narrow usage...
This can not negate when revealed effects. This is for dealing with constant effects such as Barring the Gates or Blood of the Dragon. — Cas 139
Admittedly, there are ways to gain gold that early. Perhaps The Iron Bank Will Have It's Due? Inefficient, though. Maybe The Long Plan. — neophyte_7777 1
