You should use the existing combo thread for this question.
I've done a lot of experimenting with D2. 4G is not an especially great combo, but it's better than nothing. D2 is a decent Stamina/attack layer.
Glaive works best on left spin stamina, but the extra weight won't hurt you.
Force is too square to be useful on D2. It does fine on Horusood H2 and other surprisingly square layers.
1 is too triangular to be useful on D2. It does fine on Valkyrie and other surprisingly triangular layers.
4 is a fine core disk, better than 2, not as good as 7, or 0, or 10, or 00.
The main problem with D2 is how bursty it is. It's great, it has good attack and stam, but it's weak. It needs something with a stronger spring. You're going to need something like Unite or Zephyr or Hunter. Jaggy is not particularly good at Anything. Atomic is fine, but not legal in classic.
Iron is probably your best bet for attack, better than Jaggy, but it's not great.
You don't have the right parts for a really good D2 combo. I'm sorry.
You might have better luck with X3.Force.Iron, X3 is square as heck.
