Gremlin/Deck

Gremlin uses a Darkness Dragon World focused around his Buddy Black Dragon of Demise, Death Tallica. Early game he uses Darkness Dragon World's standard abilities to reduce his opponent's resources and stall while he sends as many Deep cards to the Drop Zone as possible, either by milling, paying Gauge, or destroying his own monsters.

Once his Drop Zone is large enough he brings out Death Tallica who will have an extremely large ammount of Soul making it very difficult to take down while his opponent should already have a small hand due to his early game making it even harder for them to defeat Tallica.
