Answer 1

first, you really need to drop alot of those cards. Your deck has way to many. one way to improve your deck would be to chose a theme, like dark magician. Then you would fill your deck with cards that help you get him out like spellcasters circle, dark magic curtain, and cards like thousand knives to support it. althought this is just a suggestion, i find it to work quite well because my deck is all about protecting myself. My deck is filled with monsters that aren't destroyed by battle, cards like magic cylinder and draining sheild in case of emergency. then i also run 3 golden ladiebugs so i get my lifepoints safely in the 13-20 thousands before i charge in for and assult. even 5 3000 attack monsters directly attacking can't kill me.

If you really want to keep this deck, try to limit the size to 40-60. not sure if it has more than that but it sure seems like it. also drop some cards like karate man and some of your tribute monsters. right now, your deck seems like it is overwhelmingly large. Lastly, a tip, the larger your deck is the less likely you are to get the cards you need.

Good luck on your deck
