Correct use of EnumSet Java

I need some structure where to store N Enums, some of them repeated. And be able to easily extract them. So far I've try to use the EnumSet like this.

cards = EnumSet.of(
                BEST_OF_THREE,
                BEST_OF_THREE,
                SIMPLE_QUESTION,
                SIMPLE_QUESTION,
                STAR);

But now I see it can only have one of each. Conceptually, which one would be the best structure to use for this problem.
