D Cubed

Summoning itself from the deck is nice and being able to send cards from your deck to the graveyard is nice (no Disk Comm legal tho), but you have to discard cards in order to get these effects working.  And if you're going to discard that Malicious, you're better off doing so for a card with more utility like Phoenix Wing Wind Blast.  Like economists say, there's no such thing as a free lunch.  Moreover, this card in and of itself doesn't even do anything.  It's just a 0 Atk monster with as much utility as a Scapegoat token, and it's not even a floater since it doesn't provide card advantage.

1/5

D Cubed is supposedly a Destiny Hero, but only when it is Normal Summoned and face up. Otherwise it is just a Level 1 Dark Machine-type monster with 0 Atk and 0 Def. The stats are bad, including the name since it's only useful when it's considered a Destiny Hero. Then its effects have to be considered. There are two that can only be used once per turn. 
 
The restriction on the first effect is too much. The cost is up to 2 discards from the hand to Special Summon other D Cubed from almost anywhere up to the number of cards discarded. The D Cubed that were Special Summoned are not treated as Destiny Heroes. The cost is steep especially when you consider that after using this effect you can only summon Destiny Hero Monsters. You can set whatever monster you want, but it's still problematic to have three weeny monsters on the field after discarding so many cards. 
The second effect only triggers if D Cubed is destroyed by anything. Its destruction allows you to send a Destiny Hero from the deck to the grave. That effect would have been much better if it were any Hero monster. It can't even send itself to the grave by this effect because it is not a Destiny Hero in the deck. I'm sure some effects will activate when sent to the grave by this effect, but not enough to warrant running D Cubed.
