The challenge lies in the symmetrical nature. Targeting mechanics and the ability to strip gold status or interact with it is just the same old TCG tropes we've seen before. You don't have to ability to guarantee things anymore b/c the gold status can be removed either way, so putting down 15 STR Geralt Gold to be able to scorch the following turn because the opponent had a 12 STR non-gold isn't a fool proof gameplan.
I think it's a mistake to suggest that complexity means greater strategy. These are simply two versions of the game that require different strategy. In my mind, the consistent symmetrical approach to the game was inherently balanced and something we don't usually see in CCGs, which I enjoy. That said, of all the new changes, I am open to changing how Gold cards work more than I am drawing cards between rounds. We haven't seen enough cards to write off the new Gold card changes, or deck building changes (I do like the new bronze, silver, gold special cards).
I'm open, but remain skeptical. What appeals to me as a player the most was the symmetry of the game, meaning that your best card could, at times, be your worst card because of the board state. Being able to interact with Gold cards removes the certainty of a lot of that, which is different and currently not my taste. But, we'll see. And, I think we shouldn't undervalue easier entry level that still preserves good gameplay.
