User blog:Dnoble94/Influencing Gold Box and Silver Box drops?

Does anyone know of a way to influence what you get from opening Gold Boxes and Silver Boxes or the Chests from the Wheel of Fortune?

One post mentions to place cards with low levels in Deck #1 to get low level items or place cards with high levels in Deck #1 to get high level items. Does this really work?

Thanks.
