-1 Goblin (For Scrapyard)

+1 Veiler (Better in 2's)

+1 Scrapyard

-1 Compulsory (For Veiler, I'm just not sold on this card as a Main Deck choice. I do like it sided, though)

Just a thought.

Maybe a GK Descendant for some more destruction power?

Heh, Goblin is pretty much staple at 3, indestructible by battle + an effect that is better than scrap beast (It's the same, but being indestructible by battle change it a lot)

Spy is more than enough, no need for Descendant. Spy act as a DEF and as Arcanite Magician or Dark End Dragon non-tuner.

2 Scrapyard is already a lot, since I run a low number of monsters it's good enough to keep it at 2. Reducing my amount of monsters for it won't help much.

Think that I get my scrap dragons most of the time. Compulsory becomes so much better now (I can chain it to SD effect.)

Veiler is more of a tech card than anything, more than 1 will makes him dead more than not, and I don't want that.
