Scryfall’s advanced form exposes structured inputs for name/oracle/type, colors/identity, rarity, set/block, artist/flavor/language, numeric stats/prices, and legality-style filters; I mirrored these sections in the builder UI. citeturn4open0
The syntax model relies on field prefixes and comparison operators (ex: name:, o:, t:, >=, <=), which I mapped into the query composer and backend parser. citeturn5open0
Community usage emphasizes token-based queries such as t: and o: plus set/language filters; this reinforced the token-first approach for advanced mode. citeturn5search0
