If this card is Normal Summoned: It is treated as a "Destiny HERO" monster while it is on the field. You can only use each of these effects of "D Cubed" once per turn.● You can discard up to 2 cards; Special Summon the same number of "D Cubed" from your hand, Deck, and/or Graveyard, also you cannot Normal or Special Summon monsters for the rest of this turn, except "Destiny HERO" monsters.● If this card is destroyed by battle or card effect: You can send 1 "Destiny HERO" monster from your Deck to the Graveyard.
D Cubed can really good to help summon Plasma and/or Dogma, but the price of needing 2 discards to swarm the field and needing to have either Plasma or Dogma in your hand to summon makes it pretty difficult. You can discard a D Cubed from your hand to special summon it from the grave, but the card disadvantage is about the same. Since Plasma can be special summoned using any 3 monsters as tribute, there are better ways to summon it, but since Dogma requires at least 1 Destiny Hero monster, D Cubed can be a good option to summon it.

Why am I unable to use a normal summoned D Cubed and a special summoned D cubed as fusion materials for Destiny Hero Dangerous? One counts as a Destiny Hero, one is a dark effect monster, and Dangerous falls in line with D Cubed's summon limitation. So what am I missing here?
