Hey Jared good to see you're coming back with some revamped stars and spades. I think some of the more sought after rewards are, believe it or not, decks of playing cards actually. Haha, seriously that's the ticket. I maintain that most backers are in for 1-4 decks. The campaign numbers tend to reflect that as well with the magic number usually being 2. I think if you're running two LE's of 1000, give or take a hundred or so, decks each reward tiers offering 1 of each, 2 of each, 3 of each would be nice. The good ole Mixy brick is never a bad thing to offer either. It seems like most of the time, when we see large amounts of solo deck tiers when the decks are a set don't get taken very quickly. I imagine you'd want the momentum building as quickly as possible so, maybe leave those to a very few decks.
Things that work with decks of playing cards are fun but not always as fun as the decks themselves. Card clips once you have one or two you don't really need more, poker chips one set will do you, that kind of thing. They may end up costing more money than they bring in, like Tee's can easily do. I have yet to ever want to pick up any drinking glasses either, thought I would toss that in there haha.
I can't give any feedback on what I think your goal should be. That's going to be between you, your printer, and of course your fulfillment center unless you choose to do so yourself. Which I hear is a nightmare.
Ultimately I think it comes down to what works for you, your personality, and the personality of your deck doesn't it? I do know one thing, if you can work the international shipping so it's not such a hit, odds are your campaign will do better. That's not an easy task though, shipping always seems to take a tidy sum.
