I don't quite care about the featured cards, but they -are- excellent trade fodder-- And, for whatever reason, the Level X card, tin, and booster packs seem to to always cost less than the booster packs would cost if bought individually.
I only wish they didn't make the tins so oddly shaped... It looks cool and all, but it's really not a good shape for storing cards. It'd be cool if the tins were much smaller and suitable as a deck-box or something.
It's like buying in bulk and getting some cool extras. Hoorah tins!
