Chaos Dragon, also named Twilight Dragon or Dragonsworn is a type of deck whom combines Lightsworn monsters with Dragons to get a Chaos variant of Disaster Dragon. This type of deck became popular with the release of Structure Deck: Dragons Collide which introduced Lightpulsar Dragon and Darkflare Dragon to the TCG. The Deck became so popular recently that it is a massive force at big tournaments like YCS tournaments and even winning a few, overpowering decks like Dino-Rabbit, Inzektor and Wind-Up.
 Game Play
The main strategy is that you get future Fusion as soon as possible to dump 5 dragaons to the grave to speed up the deck, as a bonus you can summon the powerful Five-Headed Dragon two turns later if Future Fusion isn't destroyed. The Lightsworn monsters and cards (like Charge of the Light Brigade and Solar Recharge) give the deck extra speed with their Milling. With all their grave control, cards like Black Luster Soldier - Envoy of the Beginning, Chaos Sorcerer, Darkflare Dragon and especially notable: Lightpulsar Dragon, to get on the field to massively overpower the opponent. cards like the all powerful Judgment Dragon can be used in the deck as well if the deck runs enough Lightsworn monsters.
Eeven though the deck is powerful it has weaknesses, which come in the form of Skill Drain and Macro Cosmos, even Shadow-Imprisoning Mirror and Light-Imprisoning Mirror can block the deck enough to lead to it's demise in a duel, showing that cards like Mystical Space Typhoon and Heavy Storm are no unnecessary luxury.
