Choose Thornbound or Gloomborn. Each faction deck contains 42 cards total. Stack lets you flip through all 42 cards one at a time like a physical deck. Lay Out shows how those same cards are used for play: a 40-card Silverpool and 2 Guardian Dragons set aside during setup.

Monthly booster: the selection is calculated from the current UTC calendar month, so everyone receives the same six-card Preview Booster. It automatically changes on the first day of the next month. This is a Preview v1.5 feature and does not represent final retail booster collation.
