Forum:Rate/fix my deck please

So basically the porpouse of the deck is to repeatedly use the effect of nephthys by constantly summoning dark dust spirit and destroying all face up monsters on the field, then the next turn, destroy all spell and traps on the field, taking advantage of the effect of treeborn frog in your graveyard to use as a tribute fodder for dark dust spirit.

Nimble Momonga and Bubonic Vermin are there to create a barrier and use as possible tribute fodder for dark dust spirit, sacred phoenix of nephthys and for the effect of hand of nephthys.

Sangan's effect is basically to search bubonic vermin, nimble momonga, morphing jar, treeborn frog, card trooper and hand of nephthys.

Card Trooper and Morphing Jar's role is to give the deck a much needed speed boost as it is lacking of it.

Mausoleum of the Emperor is there to allow me summon of either nephthys or dark dust spirit, in case I dont have nimble momonga or bubonic vermin on the field.

Generation Shift allows me to destroy nephthys, thus activating her effect, and allows me to get another nephthys to the hand. While it its true that I can special summon her from the deck with hand of nephthys effect, it allows me to thin the deck a little.

So, what do you think about the deck? got any suggestions/fixes you want to point out? feel free to comment and hrlp me improving the deck.
