Les cinq cartes Auratog, Chronatog, Necratog, Atog et Foratog forment un méga-méga-cycle appelé "Atog" où chaque carte est parue dans une édition différente.
La carte Megatog parue ensuite fait référence à ce cycle.
Ce cycle a inspiré un cycle similaire, paru dans l'édition Odyssey (voir cette anecdote).

Source ("The original Atog was a red creature from Antiquities, Magic's second expansion. [...] It became my first favorite card. [...] So, when I realized that Mirage had a card that was essentially an Atog mechanically (i.e., it ate a resource to get a boost until end of turn), I insisted that we make it an Atog . Once that happened, I had a quest. I was going to keep putting Atog s in sets until we had one of every color. [...] So, each of the next three sets had one.")
