Not that you'd know RBD was coming when Dragonstone Port was in play.

Right. I misremembered Dragonstone Port and somehow thought the additional Player Action Window was between revealing and resolving plots, while it's actually between choosing and revealing. Sorry for that.

Derailing this topic a bit more, what are some other good uses of Dragonstone Port? The only way I can see it being very useful was if you were planning on blanking a few of your opponents saves before flipping Valar but didn't want your opponent to see it coming.
