## Search Syntax Reference

See `references/search_syntax.md` for the complete search syntax guide.

**Quick examples:**

- `o:"draw a card"` - Cards with "draw a card" in text
- `cmc=3 r:rare` - 3-mana rares

python3 scripts/scryfall_search.py named --exact "Black Lotus"
python3 scripts/scryfall_search.py random
python3 scripts/scryfall_search.py random --query "t:dragon"
