Wow, that's a lot
eek
Personally there's still a bunch of stuff I want -- either for crafting or to keep -- so I'll play a little more. I'm really far from having spent as much as you thought. You will probably need to spend a few more gold to get the stars as they are pretty elusive, but it would still give you a bunch of hearts, diamonds and wildcard too if you go the CI route from Back Alley Bargains. Or you can go with the "buy some stars on the MP" route too. Daily chance is slow, but you can gather a bunch there. I think the way you will go might depends on if you already have the Golden Fragments or not. Personally I don't, so I'm not super stressed to get them really quickly. Thought I might be careful to have enough to get the box sooner than later in case they doesn't stay there for long.
Edit: Oh and there's some in GC CIs here and there, but I dunno if there's any good and interesting one at the moment. I forgot about it since I usually go for items when I spend GC
