+
+### Database Models (16 Tables)

+- **`decks`** - User decks (DRAFT/FINAL status)
+- **`cards`** - User card collections
+- **`card_ownership`** - Card ownership tracking
+- **`win_streaks`** - Win/loss statistics

+- **`suggested_cards`** - Card suggestions
+- **`folders`** - Deck organization
+- **`game_logs`** - Game audit trail
