rate/fix disaster dragon deck?

-1 My Body as a Shield, Prime Material does the protecting that you need.

-1 Foolish Burial, there is a new choice that can work better.

-1 Prime Material Dragon, one just works so much better, two results in shitty top decking and unneeded burning of the hand, Meta right now is based largely on Remove from Play tactics, which means that PMD's effeect doesn't work that well

-1 or -2 KMD to the side deck. Drago was great last format when Blackwings and Gravekeepers dominated the meta. Now, its largely Six Sam, and Frognarchs. Drago also prevents the use of your own REDMD. I would side these, because it still counters Twilight, Lightsworn, and various other mirror matches very well.

-2 Cyber Dragon and all of the Machine Extra Decks - Cyber Dragon prevents the special summon of Totem Dragons, nothing else needs to be said

+1 Dragon's Ravine- continuous dumper.

+1to2 Vice Dragon - use these instead of Cyber Dragons

+1 Yamata Dragon - Disaster Dragon has practically **** drawpower; use this along with totem to fill your hand up

+1 Gold Sarcophagus- its up to three now, why not?

+1 Dark End Dragon - Can be reborned by REDMD, clears the front row

+1 Exploder Dragonwing - Staple 7 star Synchro for Dragon decks

+1 Trident Dragion- OTK

+1 Catastor

From your sidedeck it seems like your playing the same people over and over again. I would suggest you side Rivalry of Warlords, and if you cannot buy Solemn Warnings, get The Selection

Why dont you have Cyber Dragon, Nobleman of Crossout, and Starlight Road in your main deck? They are all cards that should be mainboarded.

i think it is pretty solid deck

these are the best UNBLOCKING sites
