The core Shub is the UT Shub with the AE illustration. Patrick McEvoy's art is replaced by John Matson's. This is the 9th core card found to be different as a reprint. I think this image is a little washed out compared to the original. I've noticed that in a couple other core cards, a kind of lack of separation between the elements.

Oddly the core Shub's collector's info "F" (as in fixed) is black, not white.
