Help with my dragunity deck?

Dragunity decks works much better if u make it a pure one.In that case u need more dragunity monsters especially dux and phalanx.U surely need a couple of dragon ravine.U can even throw in a couple of assault beast and assault mode activate cause dragunity and bring out synchros quite quickly(using the dux,phalanx,vajrayana combo).Although u dont need it,it can help.U need more d. synchros as well especially vajrayana.
