Red-Eyes Deck

Red-Eyes B. Dragon has a low ATK for its level and has no inherent effects, so many people pass it up in favor of something like Blue-Eyes White Dragon. However, while the Blue-Eyes favors simple brute force, Red-Eyes is more flexible and can grant easier access to upgraded forms, and supports multiple deck variants based upon it. Here are a few:

Hopeless Dragon Deck
The main monsters in this deck that are essential in running it are 3 copies of both Red-Eyes Wyvern and Red-Eyes Darkness Metal Dragon. This deck utilizes lots of trap cards, particularly counter trap cards like Solemn Judgment and Dark Bribe.You can combine these with Van'Dalgyon the Dark Dragon Lord to easily summon a powerful monster and use one of its useful effects. It's designed to keep your opponent's Spell and Trap card zones completely unoccupied, while you proceed with dealing heavy damage with monsters like Red-Eyes Darkness Metal Dragon, Dark Horus, Prime Material Dragon, etc.. Its a good idea to run Lyla, Lightsworn Sorceress in this deck since she makes you dump 3 cards every turn, because Red-Eyes Darkness Metal Dragon has the ability to special summon one dragon from your hand or graveyard every turn. Her ability to destroy 1 magic or trap card also comes in handy as well. Dark Armed Dragon also can make his way into this deck, since there are only 7 dark monsters in this deck, and 3 of them are going to spend most of their time on the field. Also Future fusion can help speed this deck up.

Red-Eyes Darkness Dragon Deck
A copy of "Red-Eyes B. Chick", "Red-Eyes B. Dragon", and "Red-Eyes Darkness Dragon" in your deck can lead to a rapid combo of getting out a massively powerful monster in one or two turns. The effects of "Masked Dragon" will help summon "Red-Eyes B. Chick", and basic Dragon Deck support cards should be included as well, such as "Stamping Destruction" and "Dragon's Rage" ("Dragon's Rage" will greatly help "Red-Eyes Darkness Dragon" make the most of its rapidly-increasing ATK). Most of the rest of the monsters in this deck should be Dragons, such as "Infernal Dragon", "Luster Dragon #2", and "Luster Dragon" to power up "Red-Eyes Darkness Dragon", but a few Cyberdark monsters can be added in case of emergencies. Some players also include the Armed Dragon LV series to quicken the speed of Dragons going to the Graveyard.

Foolish Burial is a good card to use in this particular deck because you can quickly send Dragon type monsters to the graveyard to power up your Red-Eyes Darkness Dragon. Vanguard of the Dragon is another good card to use in this deck because due to its effect you can send 1 Dragon type monster in your hand to the graveyard (more ATK points for your Red-Eyes Darkness Dragon) and when its destroyed by an opponents card effect you can special summon a normal monster like your Red-Eyes Black Dragon from your graveyard (send Red-Eyes Black Dragon to the graveyard to activate the effect of Vanguard of the Dragon). Ancient Rules is a very good card to use also because you can instantly special summon your Red-Eyes Black Dragon from you hand.

Fusion Red-Eyes Deck
This deck focuses on fusing Red-Eyes B. Dragon with Summoned Skull for B. Skull Dragon and with Meteor Dragon for Meteor B. Dragon. Ancient Rules helps greatly, as it can allow the free summon of any of these Material Monsters, since they are all high-level Normal Monsters. Copies of Polymerization and King of the Swamp tend to be necessary, as do card effects that can Special Summon Normal monsters from the Graveyard, like Birthright. Many of these monsters are DARK, so Dark-support cards like Mystic Plasma Zone can help. Summoner's Art can also search out any high-level Normal monster in the Deck to speed the process of Fusion. Since the fusion monsters themselves have no Effects, they can also benefit from such cards as Non-Spellcasting Area.

Cyberdarkness Deck
Similar to the Red-Eyes Darkness Dragon deck above, only with a higher focus on Cyberdarks and Cyberdark Dragon. Red-Eyes Darkness Dragon as well as the Cyberdark monsters benefit from Dragons being sent to the graveyard, and, optionally, since this deck focuses on supporting Machines as well as Dragons, Red-Eyes Black Metal Dragon is a possible inclusion (though that card is rarely used). Hunter Dragon is a good option to include here to maximize the power of the Cyberdarks.
