I haven't played this version in a while, but I ran a different Dasher deck so I have some inputs from there.

Destiny Hero - Dasher really needs to be taken to a full playset of three. That way you draw into it quickly and can maximize the number of times you can use it's effect. Card Destruction is also a good addition to help dig threw your deck faster and get Dasher into the graveyard. Probably the most glaring thing missing from this deck is Jar of Greed. Jar of Greed lets you perform some draw phase shenanigans so you have a better chance of getting off Dasher's effect. I think three of these should be run in any deck trying to abuse Dasher.

ummm unless they errata'd ha des u cant special summob it from the grave... interesting deck.

Other than Premature Burial, there's nothing in the deck that special summons from the graveyard. Destiny Hero - Dasher special summons a monster that you draw from your hand.
