"Big Money" is a fraught term because the title suggests heavy reliance on Treasures, and it was also originally understood in this way. But there is a need for a larger category of strategies which includes treasure-reliant decks, but also action-heavy non-drawing decks, or decks that have only 3 Encampments for draw, and so on. For lack of a better term, we call this deck "Big Money", but lots of people still understand "Big Money" to refer to treasure-reliant decks.
I think "Good Stuff" is a better term, but the name isn't very descriptive, and I don't think WanderingWinder originally intended Big Money to be a subset of Good Stuff.
As far as most newbies are concerned, what this deck is, is basically an ordinary deck. It's the deck type you start out with, and then later you learn about slogs, rushes, and engines. But calling it "ordinary" deck is problematic because it's only "ordinary" in novice play.
I don't know what to call it. But just throwing an idea out there, you could call it a Stop Card Deck, because the stop cards far exceed the drawing/sifting. I guess most rushes and slogs would fit that category too.
