The last three priests that I've played against that used Mindvision on Turn 1 going first got my coin.
I've only even used Mindvision twice myself, both times grabbing a coin on turn 1 when I had no other plays. After that I took it out of my deck.
I've also watched various players on Youtube using Mindvision on turn 1 going first... always been a coin.
It's starting to get to the point now when I don't think it's random chance any more.
Anyone else have their own experience to share, or is this just me?
