Forum:TCG Scrap Deck

Hi guys! I'm working with a Scrap deck for TCG. It's pretty good but when something in my combo gets destroyed, I lose most times. When Scrap Dragon hits the field, I always (until now). I think the problem with this deck is that when ive got a bad draw, it's realy slow. I tested this against 3 decks: Cyber Dragon OTK, Wrath of Neos and Absolute Zero. Like I said, I must get a good draw or else the deck is slow. I'm not sure if a mill technic is so good with Scrap. Most time Scrap Chimera is send to the graveyard and if I draw him i have already a scrap in the grave. A/D Changer was almost everytime in the grave but never handy. Another problem is that when I put the mill cards out, I don't now what to put in (there are not that many Scrap in the TCG). So here's my deck:

Sugestions please! Especially with other monsters.
