The Power Seven: Resource Cards w/ Isaac Vega

Concepts like "mana screw" and "non-games" have existed in card gaming from the start, stemming from the reality that sometimes you do not draw the resource cards you need to play out your deck. With more recent designs doing away with resource cards entirely, we call up Isaac Vega (Dead of Winter, Ashes, Rose Gauntlet) to ask if this approach to game systems still has value, or if it is simply an outdated mechanic with more downside than upside.
