Forum:Special summon Chaos Emperor Dragon

Can Chaos Emperor Dragon - Envoy of the End be special summoned from a player's graveyard under any conditions? Even if it was successfully special summoned from a player's hand by removing a light and dark monster form their graveyard from play.

"This card cannot be Normal Summoned or Set. This card can only be Special Summoned by removing from play 1 LIGHT and 1 DARK monster in your Graveyard. By paying 1000 Life Points, send all cards in both players' hands and on the field to the Graveyard. Inflict 300 points of damage to your opponent's Life Points for each card that is sent to the Graveyard by this effect."

If so, can it be special summoned after using its effect? Thanks, this will end a long argument!
