Is my Yu-Gi-Oh deck fine?

short and sweet answer is, no. First off you need to find an idea to base your deck off of (like warriors or Light monsters or an archetype like Gravekeepers or Gladiator Beasts). Second I advise you follow the Advanced Format banlist..not many people play traditional (uming you are using the trad. banlist). And 3rd, do some internet research on the decktype you decide to build which will help you learn what cards are good and what just doesn't work.
