I constructed a deck of Dark and light monsters and i was thinking of showing it up to you guys maybe you can help me with some ideas about how to make it better and correct any build mistakes .

uhhh, well, light and dark generally spells chaos decks

and yours seems more chaotici in the fact it looks like a mess

take a pic from these and I can help

twilight dragon, chaos piper, chaos agents, chaos dragon, chaos lightsworn (twilight), chaos fairy supression, chaos supression, chaos doppel junk, chaos salvo, chaos demise, chaos northwemko, chaos galahad, chaos valhalla agents, chaos valhalla fairy, ruin chaos, chaos darklord

1st No NOrmal Monsters - Ever (only in Gemini and deck with Rabbit)
2nd Side and Extra must be full
3rd The most played trap are Solemns, Torrential, CotH, Mirror Forse and Bth no need other one
4th You dont have Veiler. He is a great card here - light monster and u can easy send him to grave


You can try some Lightsworn because they mill and u need many Light and Dark in grave. Also u can try and Solar Recharge for Draw Power. Maybe Tour Gude for easy summon Leviatar Dragon and bring back banished monsters. Dimensional Alchemist will be nice if u play this deck with more monsters. There are so many variant. If u know how to play Chaos Deck i'm sure u wont have any problem with this build.
