Instant Fusion is doing better than I thought tbh

when playing Morphing Jar, consider the following: Do you really want to risk giving pluses, to the multiple decks in this format who can thin and draw like crazy and/or play their whole hand and sit on their 1st turn pluses? i.e: Sams. You should really be playing Sangan in place of jar. Especially since you're running granel. Also, Orthros. And plus:

2 Granel
2 Instant fusion
2 Warning
1 Solemn

Now since you are playing Granel, you dont want to lose Points so fast and easily.

We also have Tengu now, to float on, so the thought of Instant Fusion is really unnecessary.

Side deck wise: Go 2 Chain D, and 1 Debunk. Chain Diss is more important, and you are hardly gonna get off on debunk, its just amazing to have because of Crow and Veiler being brought in this matchup. Tech 1 is fine.

Finally in the extra: This Scrap Build, wont make Trish or Liberian on a consitant basis

so I took Instant Fusion and Jar out.

-2 Instant Fusion
-1 Jar
+1 Pot of Duality
+1 Sangan
+1 Orthors

Side Deck:
-1 Mind Crush
-1 Debunk
+2 Chain Disappearance

Extra Deck:
-2 Fusion
+1 Scrap Twin Dragon
+1 Ally of Justice - Catastor

anything else :D?

I'd say to cut the 2nd duality you've just added for a scapegoat, this card is just amazing protecting you from four attacks, providing synchro materials and provide fodders for Scrap(Twin)Dragon.

I'm cheering for Royal Oppression over Torrential Tribute (Since you'll be keen on having field presence) in your build if you know when to use it especially that you run decree (lock your own oppression before if you're about to special summon)

I'd also suggest Dust Tornado and Effect Veiler
2nd shall be there to perfect the sangan engine, while first just gives you either one for one (Pretty useful in GKs/Dragunities and somehow Six Samurais) or +1 when you chain it to either Dragons' effects.

You didn't listen to me, I told you what to add and take out. :/
I'll post my fixes here to see if you listen to me on DA.

- Atlus Scarp Deck
+ RebornShadow's Scrap deck

Try my suggestion out.
