This is the dragunity build I've been playing around with lately. It uses the White Stone/Blue Eyes engine with Cards of Consonance/Trade in, as well as the ravine engine that searches out draw fodder and of course Dragunity Dux. It has enormous potential for explosive plays mid to late game, and boasts the possibility of an early otk. With Dragon Ravine seaching out phalanx and blue eyes, this deck has one of the most consistent draw engines I've ever used. Once it gets set up, you can expect big plays pretty much every turn.
