I suspect this is going on with other decks but this is the only proof I have as it happened to me by accident. I've had a feeling folks were getting cards earlier than they should but I could never prove it because they go so fast sometimes.
What this screenshot shows is the end of my turn on round 1. On round one I went first and I had 3 coins and 2 power cards. I used the power cards to flip the Red Eagle Patron to draw another card because Midnight Raid was in the Tavern. Upon buying Midnight raid all of the cards got put back onto my draw pile and never hit the cool down or discard piles. It also put Midnight Raid on the very top. So this screenshot shows zero cards in my cool down pile, zero cards in my discard pile and 4 coins and Midnight Raid in my hand. It also shows the score for the 5 coins and 1 power the other player used on the bottom of round 1.
