The biggest thing is dropping the magical stone excavations and the dark factorys for the one day of peaces. Gives you a draw and the potential to stall for one turn if you need it. Magical Mallet is, in my opinion, better than Reload. I'd try to work 3 in, but I'm not sure what else to take out. Royal Magical Library could get you those extra few draws you need with the high spell count. And it wont necessarily be a dead draw as you're not going to be summoning anything else and it should be able to at least turn your normal summon into one (thought likely a lot more depending on when you draw into it) draw.
The mallet and library are a bit less necessary and owuld just be my personal preferences. I see your strategy here, using Dark Factory, both as a fail-safe for the exodia pieces, and a way to re-cycle blue-eyes/Flamvell Guard for their respective draw cards, as well as feuling Super Rejuv. Magical Stone Excavation plays into this combo as well, but I think the drawbacks of the cost could be greatly outweighed by more individual cards with draw power.
