Forum:Red-Eyes Darkness Dragon summon


 * Red-Eyes Darkness Metal Dragon

You can remove from play 1 Dragon-Type monster you control to Special Summon this card. Once per turn, you can Special Summon 1 Dragon-Type monster, except "Red-Eyes Darkness Metal Dragon", from your hand or Graveyard.

I can special summon from where? just my hand? just graveyard? just deck? just hand and graveyard? just hand and deck? just graveyard and deck? or hand, graveyard and deck???

somebody can explain me this plz. thx.
