Question: What percentage of cards with format commander and legal status do not have a content warning?
SQL: SELECT CAST(SUM(CASE WHEN T1.hasContentWarning = 0 THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(T1.id) FROM cards AS T1 INNER JOIN legalities AS T2 ON T1.uuid = T2.uuid WHERE T2.format = 'commander' AND T2.status = 'Legal'
