- Add MtgonlineCard model (local card data mirror in mtgonline DB) - Create user_deck.py models (UserDeck, UserDeckCard, DeckPrecedent, CardSuggestion) - Create user_deck_schemas.py with Pydantic schemas - Update decks.py router to use local MtgonlineCard instead of cross-DB MtgCard - Add migration 002 (user deck building tables) - Add migration 003 (mtgonline_cards table) - All card lookups now use local mirror for fast queries - No cross-DB joins in deckbuilding endpoints
