Visionary is awesome, and very powerfull when played right. That having said, I'm curious to hear whether anybody exists that have made good use of the power on Prophetic Vision.
Specific situations in which the villain can't play cards excluded, I find it a very a poor trade-off.
My first game against the Ruler of Aeternus in Aeternus, I saved this one for last of the Disparation expansion and was expecting a though fight.
It was quite amazing, and story-wise I don't know, to see how Setback managed to play Chain Reaction on turn 2, destroying his 3 Unlucky cards in play, burying the 3 Prince cards in play and cheesing the win since no other Villain targets were in play.
Who knew Setback in Hell could lead to something positive
