As long as the Chaos Emperor Dragon had been properly special summoned initially before it went to the graveyard, then yes, it can be resummoned by cards like Call of the Haunted or Decoy Dragon..
That's because it is a 'only be special summoned by' monster, for which the above rules apply. If it were a 'cannot be special summoned except by' monster, like Dark Armed Dragon, then you cannot resummon it from the graveyard, even if properly summoned beforehand.
I'm not sure but the best answer i could come up with was a decoy. Seems like the opposite of a spy.
Mountain: field spell increases dragons atk & def by 200. Lord of d: protects dragons Flute of summoning dragon: Lets you special summon 2 dragons when lord of d is on the field. Decoy Dragon: Lets you special summon a high level dragon from the graveyard when attacked Masked dragon: Special summon a dragon with 1500 ATK from your deck. Useful to summon Decoy Dragon which can summon a good dragon monster. It's a chain of summoning!
