A very simple and a very fun deck to use. With Lightsworn engine send LIGHT and DARK monsters to GY which can be used to summon Chaos monsters.
Use Pot of Avarice and J of Avarice to return cards back to deck, since you can get rid of most of your deck in one turn with Lightsworn engine. Burial from Different Dimension allows you to re-use already used monsters for summoning Chaos monsters.
I've used this deck againts many other decks and my average win rate is 8/2 (W/L). It can even go againts Dragoon and win.
