Atogatog is not a good card.
Though, to be fair, I honestly really like Atogatog. Flavor-wise, it’s amazing; seeing every Atog in the game on one card (at the time, at least; Megatog broke this by being printed later). As far as a 5-color commander goes, I would much rather play Child of Alara or Progenitus. Sadly, an Atog-themed Commander deck is unlikely, as there aren’t very many atogs, as you can see here.
Aboshan, Cephalid Emperor was a Legendary creature from Odyssey, and is one of the Cephalid creatures that were essentially only in Odyssey Block. While he’s no part of the legendary Cephalid Breakfast Combo deck, he’s… well, honestly, rather terrible. While he can tap other Cephalids to tap down permanents or allow you to pay UUU to tap all non-flyers down, his 4UU mana cost on his 3/3 body is terrible and doesn’t make him worthy of being a general. I will, however, go over Cephalid Breakfast rather soon, which you can find here.
(Editor’s note: As of this writing, you can order a near-mint copy of this guy for about a quarter.)
