Do u think this a good deck?

You have quite a large selection of cards. Do you have a favorite monster? ( I saw that you stated Kuriboh was cute ) Following a Theme will help you make a more workable deck and it should not be more than 40 - 45 cards big. A Theme is like using Beasts, Spellcasters, Insects or Warriors etc. You seem to have a well rounded collection, Do you have a lot of cards that will help your favorite monster? My favorite monsters are the Crystal Beasts, I like to use or include them in my deck. I would not include Toons or Fusion ( unless you are using Elemental Heroes ) in your deck cause they are hard to use most of the time. Play test your deck with many opponents so you can see what is good and what cards need to be replaced. Also go online to check to Restricted and Limited card lists and you can see many deck types on YouTube. Good Luck building a competitive deck with what you have.
