Use this card in a "rokket" Deck, since they give you certain advantages when sent to the Graveyard by a Link Monster's effect. Plus, if a "rokket" Monster on your field was destroyed, you can summon another one from your Deck during the End Phase.
The Ace Monster of the archetype, "Borreload Dragon", becomes a powerful Draw Engine when used alongside "Supply Squad". When it targets one of your "rokkets", that Monster can destroy itself and either send a card on the field to the Graveyard("Autorokket Dragon" for Spells and Traps, and "Magnarokket Dragon" for Monsters) or render a Monster unable to attack and negate its effects("Anesthrokket Dragon"). When the "rokket" is destroyed, you draw a card. Due to these Monster's effects, this effect can be repeated throughout the duel.
While you control this card, "Dimension Guardian", "Return of the Red-Eyes", and "Topologic Bomber Dragon", target this card with "Dimension Guardian" to prevent this card from being destroyed. When your opponent tries to summon a Monster to one of their Main Monster Zones, use "Return of the Red-Eyes" to summon a Normal Dragon to one of "Topologic's" Linked Zones, wiping out every monster in the Main Monster Zones except for this card.
A Guiver Deck(A mix between a "Darkness" and Mill/Virus Control Deck) can use this card with ease. The Viruses require you to tribute a DARK Monster to activate them, which gives them two purposes: To destroy the opponent's cards, and power this card up.
"Mask Change II" and "Masked HERO Dark Law", although not meant for Dragon Decks, can be good cards to use in Guiver Decks. When your opponent's cards are destroyed by your Virus/Mill combos, they will be banished due to "Dark Law's" effect instead of being sent to the Graveyard. Plus, you can banish one of the cards your opponent drew, but was not destroyed, once per turn. Plus, you have to Tribute one of your face-up Dragons to activate "Mask Change II", which grants this card 300 additional ATK.
In fact, using "Tyrant's Temper" with "Skill Drain" can cripple your opponent's Monsters, while yours will still be able to use their effects.
After equipping "Black Metal Dragon" to this card, activate "Release Restraint Wave" to destroy it, as well as your opponent's Set Spell and Trap Cards. Then use "Raigeki" to destroy their Monsters, and attack directly with this card for an OTK.
This card works well in "Cyberdark" Decks as the main aim of the deck is to get Dragon-Type monsters into the Graveyard.
"King Dragun" can protect this card and other Dragons from being targeted by card effects, which can create a lockdown with "DNA Surgery". A Deck can be built around it, with this card being the Ace Monster.
Summon "Grinder Golem" in Defense Position while you control this card and "Dragon's Rage", before attacking your opponent's new Monster for heavy damage.
This card's high Level makes it a good candidate for "Ante".
If one of your Xyz Monsters is "Number 92: Heart-eartH Dragon", "Fiend Comedian" is a good card to use. If you call it right, "Heart-eartH Dragon" will return when destroyed with 1000 ATK for every card banished from your opponent's Graveyard. If you call it wrong, several Dragons will be dumped into your Graveyard, powering this card up.
You can also use "Cyberdark" cards as support, ultimately causing this blend to become an intimidating force.
A great card to use this with is "Elemental HERO Prisma", which can both fulfill the requirement of sending a "Red Eyes" on your field to the grave, and at the same time, place more copies of "Red-Eyes B. Dragon" into the Graveyard for future cards such as "Birthright" and "Swing of Memories".
A good card to combo with this card is "Armed Dragon LV5" or higher "Armed Dragon" monsters. By sending Dragon-Type monsters to the Graveyard, with "Armed Dragon LV5's" effect, you can increase "Red-Eyes Darkness Dragon's" ATK while still destroying your opponent's monsters by discarding cards like "Blue-Eyes White Dragon". "Darkness Dragon" can easily become more powerful than those monsters. You can also use this card after Summoning "Blue-Eyes Ultimate Dragon" because this card can gain 900 ATK for the 3 "Blue-Eyes" in the Graveyard.
If you send Dragon-Type Normal Monsters to the Graveyard with the effect of "Spirit Ryu", you power up "Red-Eyes Darkness Dragon" permanently while giving "Spirit Ryu" 1000 ATK for each monster sent (but only for the turn).
You can equip this card with "Red-Eyes Black Dragon Sword", which will give it 800 ATK for each Dragon in your Graveyard. Said Fusion Monster is particularly helpful with this card, as Red-Eyes Darkness Dragon's ATK can reach around 5000 even if the number of Dragons in your Graveyard is at a minimum, and this card will have 3900 ATK if neither you nor your opponent have a single Dragon in your Graveyard(Although such is very unlikely).
A "Meteor Black Comet Dragon" that was Fusion Summoned by "Red-Eyes Fusion" can be Tributed to Summon this card. The effect of "Meteor Black Comet Dragon" can then be used to Special Summon a Normal Monster from the Graveyard. Alternatively, if "Meteor Black Comet Dragon" is destroyed by your opponent, you can use its effect to revive a "Red-Eyes B. Dragon" to Tribute for this card.
Choose this card when you activate "Last Turn", to send any remaining Dragons on your field or in your hand to the Graveyard. By the time you activate said Trap, this card's ATK will likely be high enough to destroy the Monster your opponent summons.
This card can spell doom for "Apoqliphort Towers". "Towers's" effect based on Special Summoning doesn't matter, since this card is empowered by the Dragons in your Graveyard, and this card will destroy it by battle on your turn, assuming you have at least 4 Dragons in your Graveyard. Plus, when your opponent forces you to send a monster to your Graveyard, you can pick one other than this card to give it an additional 300 ATK.
In fact, you can use the effect of "Return of the Red-Eyes" to revive a Normal Dragon from your Graveyard anytime "Towers" forces you to send a monster to your Graveyard, and then choose the monster you just revived, rendering "Towers's" effect useless.
Since many archetypes focus on one Monster type, "Tribe-Infecting Virus" makes a deadly addition to an REDD Deck. You can discard a Dragon to power this card up and destroy many, if not all, Monsters your opponent controls. There is no limit as to how many times you can do this in a turn, either.
While you control a "Meteor Black Comet Dragon" and "Pandemic Dragon" activate "Cold Wave" to pin down the Spell and Trap Zones. Afterwards, use "Pandemic Dragon's" effect to pay enough LP to reduce your opponent's Monsters' ATK to 1000 or less, before summoning "Red-Eyes Darkness Dragon". Afterwards, summon "Red-Eyes B. Dragon" with "Meteor Black Comet Dragon's" effect and attack your opponent's Monsters for an OTK.
Tribute Summoning "The Tyrant Neptune" using this card and "Five-Headed Dragon" will result in you gaining a Monster with at least 7400 ATK and 7000 DEF. Give "Neptune" this card's effect so that its ATK will continue to rise. If you have a minimum of 9 Dragons(Including the aforementioned Monsters) in your Graveyard when you Tribute Summon this card, it will have at least 10,100 ATK.
If you roll either of the numbers you declared with "Sixth Sense", you will draw more cards. Otherwise, you run the risk of sending more Dragons from your Deck to the Graveyard.
