They stopped censoring Ankhs quite a while ago. (And did so inconsistently even before that. Silent Magician LV8 and Hysteric Fairy didn't lose their Ankhs. Heck, it took them five years to notice Book of Life even had one.)
Also, IMO, the TCG Reborn has better art. (And the OCG seems to agree it's good, too, since Monster Reincarnation's art was based on it, and they got the TCG art recently.)
And they still haven't noticed Book of Life actually has three ankhs on its artwork, not just one.
They changed it. Its like the millenium key only with green as its color. Censorship matters in konami. They removed all the crosses and pentagrams in the game. Put clothing in cleavages in the girl characters
