I did read that "All Seven Drops (Secret Lair Bundle) – December 2"
So I guess the availability of each "set/box" is called a drop
All 7 costs about $199
I see people saying there are “4-8 cards per box.” and that will include tokens.
The Drop Series consists of different "drops"—each of which is a standalone product that takes a small group of cards (usually three to five) selected around a particular theme, gives them new art (sometimes really wild new art), and then wraps them together in a customized collectable box.
