Thethewes,

You may have to settle for grinding for Batman/Arkham Origins. Harley Quinn/Arkham   has a very low drop rate from the  Gold Booster Pack, and you should not count on it as a way of promoting her. The best way to obtain  Arkham   characters,  by far, is through the buying of the  Arkham Pack. Sadly this pack was removed from the store around a month ago, but my fingers are crossed that it will come back soon.

Good Luck,
