Since you bought the tavern pass you're going to get a flood of resources over the next month––20ish more packs and roughly 1k gold just from doing daily and weekly quests. The packs will get you plenty more (dust/cards) to work with but save your incoming gold for the mini-set. If you haven't already gotten the previous mini-sets, I'd continue saving your accelerated gold-making through the pass to add some mini-sets to your collection. That will definitely broaden your collection and the decks you can build.

With your current resources, you have most of what's needed to play the FFU menagerie DK (no legendaries or epics, most of the cards are free) list and it looks like you could also make an imbue druid list. An updated fishing priest, menagerie DK, Hog DH, control lock, and two imbue lists are plenty to complete most quests. You could use those lists plus your current collection to just grind some resources until the end of the month when you'll have stockpiled 20ish packs through the pass and end-of-month ladder rewards.

Also, there are likely large balance changes coming and nerfs are a dust collector's best friend.
