The deck grows by its own draws
From 28 October on, the deck grows only when two of its own cards call for it. When The Sower is the morning’s card, one new card grows from a seed that comes from outside the deck: something from the day, a random page of a book, a sentence someone else said. When The Miner is the morning’s card, one new card is dug from a gap between two cards: a meaning the deck circles but no card holds.
Only the morning’s card counts, upright or reversed; the lens card never does. Chance decides when: two new cards may come in one week, or none for months.
Each new card is announced here, and its page names the morning that called for it. The rule is on the about page.
