"Dark Magician" monsters have several features in common:
The armor of most "Dark Magician" monsters is a collection of shiny, curved plates with sharp edges, all of the same color, which covers the torso and shoulder areas. On the edges of the plates are curved trimmings of contrasting shade.
Some of these monsters also have hats which appear to be similar to a stereotypical wizard's hat, which is usually crooked, leaning forward at the tip and with several rings which segment it. These rings are of the same color of the curved trimmings seen elsewhere on its attire.
Some of these monsters have Spell Counters embedded in their staff, shield, sword or armor.
Some also have the Arcana Seal depicted in the background.
The monsters of this archetype are fairly strong on their own, however, they rely a lot on a large amount of support cards to keep them going. The later releases revolve around spell counters. Depending on the way the Deck is built, this archetype can be very slow or fast archetype, occasionally able to out-trump even the "Blackwings", or the "Six Samurai" depending on the draw and how often "Dark Magician" can be Special Summoned. "Magical Dimension" is a great card in order to rush your "Dark Magician" out fast. Protecting a "Skilled Dark Magician" as he gathers up his counters is another way to go, but this strategy relies on how many spell cards you can allow your opponent to play before they gain the upper hand.
This archetype also lacks support, with only "The Eye of Timaeus" supporting the archetype as a whole. Most support for cards in the archetype is for "Dark Magician" himself or Spellcasters in general.
