Chaosworn

Lightsworn and Chaos, a combination almost as old as yugioh itself. Personally, I don't play creator or valkyria, but both can be used as extenders so feel free to adjust the deck. Very simple deck, summon raiden or lumina then raiden, mill, extend (graveyard effects, minerva, special summons, etc), build board. Its quite easy to put up a few interrupts like harbinger, crystia, apollousa, and draco berserker. harbinger can be made with chaos ruler and levianeer. Levianeer can very easily summon apollousa, etc. It struggles against spell/trap heavy decks going first or second so the side deck has backrow removal. It also struggles going second so extra cards like hand traps etc are helpful there. The easiest out to a boss monster is dingirsu. Enjoy.
