Lightsworn

Lightsworns, known as Lightlords (ライトロード) in Japan, are a set of monsters introduced in Light of Destruction. Their primary effect involves self-milling, sending cards from the top of your Deck to your Graveyard, either as a cost to activate their effect(s), or as part of the effect(s) itself. This, except that it may cause you to deck out if you aren't careful, is very good because many Lightsworn cards work well if you have many Lightsworns in the graveyard, like "Gragonith, Lightsworn Dragon" and "Judgment Dragon", and another Lightsworn monster - "Wulf, Lightsworn Beast" - is Special Summoned when sent from the Deck to the Graveyard. Also, if Realm of Light is in play while a large number of cards are sent to the Graveyard, it will drastically increase the attack power of all the Lightsworn monsters on the field.

"Pot of Avarice", "Magical Blast" and "The Transmigration Prophecy" may help replace some of the discarded cards, reducing some of the side-effects of self-milling."Solar Recharge" and "Card of Safe Return" can add even more speed to the Deck. In the OCG and TCG, many players are using Lightsworns to counter "Dark Armed Dragon" Decks, because of their field swarming capabilities. This Deck is quite capable of a very fast OTK using their mill effects, and then summoning "Judgment Dragon", or by using "Glorious Illusion" if you have strong Lightsworns in your Graveyard. "Judgment Dragon" alone would easily be able to create an OTK situation fairly quickly. Lightsworns have currently seen much success in the TCG, and have been considered a "metagame" archetype. Lightsworn Decks are also some of the most successful and popular Decks in Yu-Gi-Oh!, and have joined the ranks of top-level Decks like Gladiator Beast and Teleport Dark Armed Decks.
