I am guessing that some of you will be buying complete sets of the base cards or inserts from these series since it's pretty hard to assemble them by buying cards individually and paying for multiple shipping costs (or just not collecting the base/inserts from these sets). If so, you may wish to trade any base or inserts you get from opening packs.
I am interested in trading for these base/inserts (don't care whether they are duplicates of ones I have) and possibly for some costume cards. If you have a few, I am also happy to trade away my common autos from these sets or from many others.
