    【Question】
    What is the passing class of CLB team? passing class refers to buildUpPlayPassingClass; CLB refers to team_short_name = 'CLB';

    【Evidence】
    passing class refers to buildUpPlayPassingClass; CLB refers to team_short_name = 'CLB';

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT DISTINCT t2.buildUpPlayPassingClass FROM Team AS t1 INNER JOIN Team_Attributes AS t2 ON t1.team_api_id = t2.team_api_id WHERE t1.team_short_name = 'CLB'
