Here's my idea:

Stick to a 3 wave a year thing for the first 2 years. 6 figures a wave, all in minimalist packaging(I'm talking Star Wars Vintage collection minimal). Card art must be bright and colorful, ditch black all together, as it makes your product blend in on the shelf. You need to grab people's attention with this line, and thus you need it to pop.

Now, 18 figures a year might seem a bit small, but as a trade, you make the figures fully articulated and can focus your efforts. Don't forget to mix in a two pack or exclusive in there, too. If the line works after that 2 year period, then go ahead and expand as you see fit.
