Dragon Fury-Cyven
Hey, this is my first tip ever, so I'm gonna start off with the deck I use, the Dragon Fury deck.
I know many people think this type of deck won't get you far, but even in its unfinished state, this monstrocity has defeated Chaos decks, Exodia decks, Control decks, Beatdown decks, Deckout decks, Hand Destruction decks (though just barely, still a weakness here...) and Burn decks.
 
One might think this is impossible since Dragons usually don't have the best effects, but the key is balance... You see, most Dragon decks have the standard Lord of D, Flute and Blue-Eyes White Dragon. Usually all of these in threes... True, old Blue-Eyes makes a great 3000 beatstick, but there is a much more lethal Dragon available... The mighty Tyrant Dragon. I don't know if people know this card, but for those who don't, here's the full info:
 
Main Type: Fire
Sub Type: Dragon
Level: 8
ATK: 2900 / DEF: 2500
Effect: When there is a monster on your opponent's side of the field after the first attack of your Battle Phase, this monster can attack once again during the same Battle Phase. In addition, negate the effect of a Trap Card that specifically designates this card as a target and destroy it. If this monster is Special Summoned from the Graveyard, you must offer 1 Dragon-Type monster on your side of the field as a Tribute.
 
Isn't she a beauty? Basically what you have here is a BEWD with 100 less attack, but it may destroy 2 of your opponent's monsters (seriously, anybody still using the old Labyrinth Wall?), which means that you will oftenly have an open field so one of your other Dragons can go on a direct-hit rampage. Also its Trap-negating effect works miracles for me.
An opponent once tried to activate Enchanted Javelin on Tyrant Dragon... poof, negated and destroyed. Next turn: He tries to activate Magic Cylinder on Tyrant Dragon.. buhbye!
 
Moving on to the next wonder:
Jinzo killer, a.k.a. Kaiser Glider
 
stats:
Main Type: Light
Sub Type: Dragon
Level: 6
ATK: 2400 / DEF: 2200
Effect: This card is not destroyed as a result of battle when this card battles with a monster with the same ATK. When this card is destroyed and sent to the Graveyard, return 1 monster on the field to its owner's hand.
 
Another magnificent Dragon I love using. His returning effect is a real pain and I (ab)use it whenever I face say Buster Blader or Dark Paladin. a nice kamikaze attack is usually all it takes to take the lead in a duel. Also, (and more importantly) Kaiser Glider can kill Jinzo and live, LIVE I TELL YOU! *cough* uhh yes.. I just love using him to kill off an opponent's Jinzo
 
I realise this tip is becoming quite lengthy, but I don't feel like stopping now... So onwards I go!
 
Lord of D. is a must have in any Dragon deck, imo. Not just for the Flute effect, but its effect protects Dragons against any targetting effect! Use this card combined with DNA Surgery and you just got yourself a non-targettable face-up field. I recommend using 2 of these in your deck, since 3 is excessive and 2 is just too few ^_^;;
 
The best trap for Dragons is most likely to be Dragon's Rage. I can't believe they made this baby a common (woot for me!), I've won so many duels because of this card.
Example:
 
Opponent has 2200 lp's left. 3 scapegoat tokens and a Vampire Lord, your field consists out of Dragon's Rage and Troop Dragon (great stall card). Summon another Dragon (say a Luster Dragon #1) and congrats, you've just won the game.
 
What Dragons should fear most though, are the notorious Jars and DD Lady's. That's why I also use Light of Intervention, at least this way you know what you're up against. Funny thing is your opponent often forgets it's already out there. I've faced plenty of opponents who (after their Witch was destroyed) would still search for Fiber Jar, while Light of Intervention was active, not only destroy it, but still try to set it, whilst it wasn't even their ownly monster.
 
In short, a Dragon deck should try to have the following:
 
*Powerful Dragons with good effects to back them up
*Lord of D's to keep your opponent from using say Exiled Force or Change of Heart
*Dragon's Rage for trampling your opponent silly
*Light of Intervention (or another perhaps even Royal Command) to stop those nasty flip effects.
