Forum:Help with dark armed dragon!

Some monster such as Judgement Dragon can be special summon even from the graveyard if you have 4 lightsworn monster in your grave. But what about dark armed dragon? If you want to special summon it, you must have exactly 3 dark monster in your grave. If you want to summon it from the grave, does it include him as the 3rd dark monster? or must have another one in your grave which means 3 dark monster, not includeing dark armed dragon? or you cant summon dark armed dragon from the grave?
