As far as I remember, the product lineup was released across four chapters.
Only the First and Second Chapters had starter decks available for sale.
My memory may not be perfect, though.
The Third and Fourth Chapters were produced in extremely limited quantities and are extremely rare.
There are hardly any images of them available online.
Anyone who owns them is incredibly lucky.
