Can someone please give me some advice on my Yu-Gi-Oh! deck?

you have way to many monsters, whether its for casual play or not you need to find cards tht mean something, even if its not a deck that is based upon certain monsters. i personally have about 20 monsters, 13 spells and 7 traps keeping t to a minimum of 40 cards for my deck and then add what ever cards for my extra deck as necessary. keeping monsters to a minimum is the bet a to allow yourself to draw thm making any strategies you may have easy to do as fast as possible. also themed decks are also the best type of deck to get used to the idea of building decks(not to sound paronising) andthen you can go custom. hope this helps.
