If everything goes as it should (there is not reason for to think the contrary) will be more expensive later to get in ... so far they have done an excellent work in the Art of the cards and reading the updates more new stuffs are comming pretty sun ... you should not wait so much, at least to have some of them ;) and this is not an investment advice XD ... but it is.

Pd: It is crazy that already you can buy and sell cards outside the web.
