The point of the deck is to turbo out your Chaofeng and lock your opponent out of using Fire type monsters. However, using Denglong you can also lock your opponent out of any other type. It always locks lights, so once it hits the field you are insulated from Nibiru. A typical end board might look something like Chaofeng, S:P, Crocodragon, and Kashtira Fenrir.
The deck might look awful, and maybe it is, but I think it has potential if you find a better secondary engine than Naturia. This was mostly constructed for fun, but holds up decently well in the current meta due to the high non engine count and the anti-fire strategy.
