Dark Army

This deck mainly focuses on the dark magician archetype.

I personally consider this as a swarm deck because of one card: Eternal Soul.

Eternal Soul is a card where on either players turn, can summon a Dark Magician from your hand or graveyard.

Then, Eye of Timaeus will allow you to summon either the following: Dark Cavalry or Dark Magician the Dragon Knight.

For powering up all of your DARK attribute monsters, Wee witch's will do just that.

I also have played this deck on Yu-Gi-Oh! Dueling Nexus and a similar deck in Yu-Gi-Oh! Duel Links, which is really fun to play with.
