Forum:Dark Magician/Counter Deck Advice

So basically I have a couple questions. -I want to add another breaker, what should i take out? -Is Dark Magic Attack worth running in a 45 card deck? -Should i add a Royal Decree? I had it, but it was never useful to me so i replaced it with CotH. -If i wanted to add a synchro Arcanite Magician to my deck,(Since tempest magician is rare) which tuner monster should i add?(like how many stars should it be.) -Should i add a diffusion Wave Motion or a jinzo? -What major flaws (besides saying dark magician is weak) do you see in my build? -Please suggest other cards that would help my deck, ideally monsters that destroy spell/trap/monsters, as that is what i lack. My deck was 40 cards, but it lacked monsters so i added the apprentice magicians and old vindictives. I have won more duels now, so i would like to keep it around 45 cards right now. Thanks for reading all this lol.
