Move the card, move the deck
When a deck is backed by a box, its physical rows and deck rows stay connected through the same location model.
DECKS
Decklists can be real boxes, not just intentions.
A Tradepost deck can stay a normal list, or it can be backed by a physical container. Materialize cards from your collection, buy a precon into the right printings, and keep the list tied to what you actually own.
Accounts open in batches during the public playtest.
Build from what you own
Turn intent into inventory by sourcing rows from your collection or materializing known product printings.
Test before buying
Pure list rows can become physical over time, while goldfish and playtest work stays clearly marked as in testing.
