Scuttling Shrapnel 75 cards, 15 sideboard 4 {Swiftwater Cliffs} 7 {Mountain} 5 {Island} 4 {Darksteel Citadel} 20 lands 4 {Generator Servant} 4 {Scuttling Doom Engine} 4 {Chief Engineer} 4 {Goblin Rabblemaster} 4 {Ornithopter} 20 creatures 4 {Lightning Strike} 4 {Magma Jet} 4 {Ensoul Artifact} 4 {Stoke the Flames} 4 {Shrapnel Blast} 20 other spells Sideboard 3 {Stubborn Denial} 3 {Polymorphist's Jest} 2 {Cranial Archive} 2 {Stormbreath Dragon} 3 {Tormod's Crypt} 2 {Phyrexian Revoker} 15 sideboard cards

Looks like a really solid list. Only thing is I might drop a couple {Chief Engineer}s as you only need one to stick. 2 has been the best for my similar build called Ensoul Blast.
