I've played them, but I can't honestly say I know enough about them. Anyways, I'd change it to the Chain Material Variant, using Primarily Stealth Union, and Jumbo Drill. You would run 2-3 Chain Material which wouldn't destroy your fusions because of Vehichroid Fusion. Anyways here's what it would look like...
-1 Polymerization
-1 Super Polymerization
-1 Power Bond
-2 Machine Duplication
-2 AmbulanceRoid
-2 RescueRoid
-2 Ambulance RescueRoid
-2 Barbaros
-1 Grandsoil
-1 Lightning Vortex
-1 Hand Destruction
-1 Magical Cylinder
-1 ShuttleRoid
-1 Book of Moon
-1 Magical Cylinder
+1 Supercharge
+1 Expressroid
+2 Torrential Tribute
+2 Stealthroid
+3 Stealth Union
+2-3 Chain Material
+3 Magical Merchant
+3 Elemental Hero Prisma
+1 Sangan
