A D.D. Deck revolve around card banishment, commonly used in conjunction with other cards such as "Golden Homunculus", "Gren Maju Da Eiza", the Helios cards, "Caius the Shadow Monarch", etc. Other cards also return themselves from banishment: "D.D. Survivor", "D.D. Scout Plane", etc.
Because D.D. is often associated with the "Sparrow Family" the D.D.'s strongest monsters overall are "D.D. Esper Star Sparrow" with 3000 ATK, and their strongest monster is "D.D. Jet Iron", with 4000 ATK. However, these two cards are much more affiliated with the "Sparrow Family" than D.D. and do not share the D.D.'s usual banishing strategies. Beyond them, however, D.D. monsters are rather weak in terms of offense, with no other monsters in their family having ATK higher than 1800. Furthermore, while there are D.D. Spell and Trap cards, the series lacks any D.D.-specific support. This lack thereof, combined with a low average ATK, make it difficult to create a Deck with only D.D. cards.
