I understand this is a big accusation. Please trust that myself and a friend have gone through the videos of the Gencon final and semifinal games over and over to make sure we are absolutely certain.
Unfortunately there is no question. In the final match of the of the Conquest US Nationals game posted on Team Covenants YouTube channel, you can repeatedly see the winning Eldorath player draw three cards in the HQ phase instead of two.
To observe this, I recommend watching the videos below on both fullscreen and 1080p. If you freeze-frame watch (you have to be as quick as you can, stop every fraction of a second, he's very fast and subtle..) the Eldorath players draw in rounds 1, 2, and 3 during the HQ phase at 3:39-3:41, 9:06-9:09, 12:14-12:17 respectively in the Final match, and rounds 1 of the semi-final game at 5:31-5:34, you can clearly see that the player is drawing three cards instead of two.
Please know that I'm not here to ruin anyone's day, or anyone's experience with Conquest. That being said, given the level of this tournament, I feel its something the community should know about.
