j.D (whiff), instant j.2C, 2B, 2C, 623C seems to be the optimal combo now when magnetized, since 6C, j.2C, 2B, 2C etc doesn't work anymore. Only chars they don't work on is carl and makoto. 5C, 6B, 2C works on Rachel after 623C whiff.
B+C, Astral works in the corner too, and mid screen when magnetized.
Also, j.C (whiff) j.B pick up seems to be easier now.
Most damaging combo I've tried:
J.2C, 2B, 2C, 623C, 623C whiff, j.D whiff, j.2C, 2B, 2C, 623C, B/Egadget = 4077.
I've yet to try an FC 2C combo that exceeds 4k. Highest I got was along the lines of 3.8k
Btw, seems that 6A is also air unblockable now.
