"Different Dimension", usually abbreviated "D.D.", and called
"D.D." revolve around card banishment, commonly used in conjunction with other cards such as "Golden Homunculus", "Gren Maju Da Eiza", the "Helios" cards, "Graverobber's Retribution", "Caius the Shadow Monarch", etc. Other cards also return themselves from banishment: "D.D. Survivor", "D.D. Scout Plane", etc.
These cards are not without their weakness however. "Imperial Iron Wall" will effectively shut down nearly all "D.D." cards (with the exception of a small few like "Different Dimension Dragon".) 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, "Different Dimension" monsters are rather weak in terms of offense, with no other monsters in their family having ATK higher than 1800. Furthermore, while there are "Different Dimension" 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, which means that "D.D." cards are more commonly used as a sub-type (mostly in "Banish" Decks).
However difficult, it is possible to have a sound "D.D." primary Deck, for cards such as "Homunculus", "Eiza" and the "Helios", gain attack and defense points multiplied by a certain number to your/both your and your opponent's banished cards. In a "D.D" Deck that focuses only on banish cards, these monsters can become a massive threat to your opponent, continually gaining in power. Also, the effects of "Imperial Iron Wall" can be remedied by running Spell/Trap Cards that destroy other Spell and Trap Cards, such as "Mystical Space Typhoon", "Dust Tornado", etc. In addition, "Monarch" monsters can also facilitate this process, and, if the proper card is present; ie, "Dimensional Fissure", and "Macro Cosmos", also banish them, and possibly damaging your opponent in the process with cards such as, "Thestalos the Firestorm Monarch", "Caius the Shadow Monarch", and the worth mentioning (however not a "Monarch", "Super Conductor Tyranno", with which you can keep recycling "Survivor" and/or "Scout Plane" to damage your opponent each turn.
Macro Monarch Deck
Macro Beatdown/Beatstick Deck
The main purpose of the "Macro Beatdown" Deck is to banish as many of both you and your opponents cards as possible in order to power up the "Helios" monsters, "Gren Maju Da Eiza" and "Golden Homunculus". "Necroface" can become very powerful if used correctly and "Bazoo the Soul-Eater" gets more powerful by banishing cards. One popular combo is to banish as many cards as possible and use "Return from the Different Dimension" to bring back "Eiza", "Homunculus" and "Helios Trice Megistus" to attack for game.
"Different Dimension Mill"/"Burn" deck revolves around banishing "Necroface" as fast as possible through "Gold Sarcophagus" and "Allure of Darkness" with either "Macro Cosmos" or "Dimensional Fissure", then hitting your opponent with "D.D. Dynamite" and a powered up "Gren Maju Da Eiza".
This deck is considered dead due to the moving of Necroface to limited status.
