Those passes are useless unless you are in a club. Then they have several uses:
(1). The club can get the same EXP points that you do when you use the pass before you play. If used for your first game of the WGT day, the club gets your CDP bonus the same as you do.
(2) The pass can be used for a Clash round (only clubs are in the Clash)
(3) The pass can be used for a Turf War round in a coin room. (Only clubs are in TWs.) If you win the round, then both you and the club get the coins. Well, the club doesn’t get the coins, but the club gets the points represented by the coins, to help win the turf War. Winning a Turf War gets the club a blue pass for use in Clashes.
