The main strategy of the deck is the basic Dark magician combos. however Magician Of Chaos adds in a more offensive Ability. I have Teched in Dark Magician Girl with Dark Burning Magic because of the fact dark magicians have a built in Raigeki and Harpies Feather Duster in one card. However if you wanted, You could remove those two and the deck would function completely fine without it, The main deck count With DMG and Dark Burning Magic is a 42 card deck.
Other useful cards for the deck would be another Dark Magic Veil in place of Monster Reborn. I went with a M.R at the moment because of the fact it can revive any monster I need. but it can also disrupt my opponents plays if need. If you wanted to play a more casual set up, then you could swap out the 2 copies Infinite Impermenace and Called By The Grave for Thousand Knives or Dark Magic Expanded. Other Cards worth of note that i prefer to use are the Mirror Forces and Solemn brigades.
