If the above quote is correct, then ALL monster with similar summoning conditions are NOMI monsters.chaosruler said:blue-eyes shining dragon and red-eyes darkness dragons are both examples of "nomi" monsters
nomi monsters can only be special summoned one way (or two, dealing with Level Up! compatable monsters), and that way is normally in the card text
YOU CANNOT special summon these monsters by any other means, (except Level Up!), and you CANNOT special summon them back even if they were properly summoned
Examples : Silpheed, BLS-EOB, Choas sorcerer, Berserk dragon, Exodia Necross, Harpie lady Sisters, Chaos emperor Dragon, Gigantes, ...
