I bought the Aristeia collectors for the metal version of the core box and i am glad i did. The plastic versions of them... are not great. Definitely not quality that i have associated with CB miniatures. I understand that they are board pieces and low quality plastics which is what has made me hesitant on buying the expansion sets. Can anyone who have bought either of the two sets tell me if the quality of the miniatures are an improvement over the ones core set or not?
