Okay, with the latest FAQ 3.0, and with The Viper's Bannerman becoming a restricted card, I'm looking at the list that Martell has now and wondering if we've now reached a point where there are too many restricted cards?
Sure, Viper's Bannerman is a powerful, pretty efficient card, but it's also something that costs 7 Gold. Comparatively, something like Edmure's host can cost as little as nothing (my experience with Riverrun decks) and still lend 6 STR to a challenge.
On the point they made about getting around the draw cap with Viper's Bannerman, why not simply Errata the response to read: Draw 2 cards? That way, if you try to use Vipers Bannerman purely for the draw effect in one round, it will only net you 3 cards still.
I'm too new to the game to know if they've ever UN-restricted cards, but I'm hoping they will with this.
