It's only semi-nomi to the point of being a fusion monster. It can't be special summoned directly from the grave as Summer suggested, but it can be special summoned (different from proper fusion summon) directly through the Extra Deck through Cyberstein, Metamorphosis, Dragon's Mirror or Summoner of Illusions. If not fusion summoned properly, cards like Monster Reborn don't work because the fusion monster wasn't summoned through the correct way. This also happens if a monster's summon was negated through cards like Solemn Warning and Solemn Judgment. If it was summoned correctly through fusion summon, then Monster Reborn will work fine unless the card itself has a clause stating it can't be special summoned and can only be fusion summoned (examples being most of the Omni-heroes).
