Yeah as someone who started last month just before Naxx came out, I also recommend just using your real life money if you can. The naxx cards are still useful and getting a lot of use in some decks, but you get more cards from buying packs/doing arena. I personally do arena instead of buying packs but depends whether you enjoy that or not I guess.Are the Naxx wings really worth the gold? I'm a fairly new player and I feel like just buying roughly a card pack a day is more worthwhile then saving 700 gold and only getting four cards that the meta is probably not going to call for.
