Is this a good yugioh deck?

Yes this is a good deck, but I think you should have a based deck instead of this deck. If you do not know what a based deck is then a good example would be a dragon based deck, they are good for attacking and special summoning other dragon cards for backup if another becomes destroyed. Another good example would be a morphtronic/machine based deck, they focus on protecting your life points and the other morphtronic/machine cards currently on the field. Basically a based deck is a deck that revolves around one type of card or a group of name connected cards like the X-Sabers or Morphitronic. Based what I just said I think your deck could use some extra editing if you were a contestant in a Yu-Gi-Oh tournament, but since you must be new at Yu-Gi-Oh or you haven't played in a while, then for now I think that your deck is quite good. (The reason I think you are new or returning player is because an experienced Yu-Gi-Oh player learns to trust his/herself's judgement when they contemplate the quality of their deck. You however are currently asking random people on the internet about the quality of your deck, how do you know if they are inexperienced, lying, or telling the truth?)
