Most of the cards you have are "free" cards you can drop in events. You have a lot of super strike cards, they are pretty good if you upgrade their Super Attack to 15 but they are not better than some cards you can only drop in portals.

You should maybe wait the 21th of december, a new portal with kaioken goku will be available :)
