So I decided after many months to buy packs for once. I went with 7 for 10 bucks, and I'm basically treating it as a donation to a game I enjoy.

I got a total of 150 dust from those seven packs, and ten cards added to the collection. (Note, I had two of the non-golden versions of both golden cards, but I am a crazy completionist who can't dust them.)
