Although the whole card of DCD has no front shell, from the perspective of the black history of DCD, DCD is the initial knight, that is, the "origin", and the late knight is actually a branch of its ability, and DCD has traveled the world of the original card Kabuto, so the DCD without amnesia, that is, the war ghost, can theoretically become an unbroken Kabuto. It is true that war ghosts can use other knights' abilities without changing their forms because they are "origins", but the ability to become other knights is still alive.

But the DCD after amnesia should not be able to do it, because his cards are limited, most of them are sealed, and he has no memory and ability as an "origin", so he can't use them.
