I don't even know any instance when the *frequency* of t/t changed mid-release. Please give me an example.aleksandr wrote:The frequency of how some of the t/t appear may change, but I have not yet seen an example of new backs showing up mid-release of a set. I draft twice a week and usually see a large sample of cards and I've never seen an example of a brand-new back showing up that has never been seen before.
We don't even have good data on what the frequency might be if it was static. We don't generally track the quantity of front/back pairs (although some may track the number of "swaps" they have which remain to them).
What I suspect happens is that a supplier may shift from US English to Euro English (or vice versa), in the middle of a release. This could have the effect of causing a shift in the front/back pair population.
