Can anyone advise me on my Dark Deck Please?

i would go heavy on the magic and traps than monsters. maybe 15 good monsters and the rest split with magic and traps. if you have the right ones that compliment your monsters, winning is a breeze. also get the cards like princess of tsurugi that do 500 damage per card in oponents magic zone. princess of tsurugi and just desserts in one turn can do 3000-5000 damage on life points easy.
