Time to post an old one I found a while back.
Dash in for the loop, placing the j.5d as close to the corner as possible.
Jump back for the secondj.2c knockdown, stein cancel late, close to the ground with j.6{D}
That's it.
The strength of this setup is that you get three 'points' on offense before the charged stein combos off your third action or allows you to reset pressure after your third action. Every Gatling essentially consumes 1 point, where 6b consumes 2.
Things that combo that really shouldn't combo but combo anyway because µ is cool, due to this setup:
2a/5a/5b/6a meaty (blocked) > 6b (hit) > 214d startup > }D{ > 214d hits > Walk Back > 6c > SoD~ > 6a > j.2c > j.5d > 66~2b > 6a > 2c > j.2c > repeat the setup with j.6{D} = 3918
if the 6b is blocked, continue the 214d input, as they will not be able to punish the startup due to the stein firing. Reset pressure during 214d.
You can also perform a second gatling before 6b and still have the stein combo off it, but you must special cancel the first hit of 6b, it's first point, as opposed to the second, for a total of 3 pre-laser.
This also allows you to combo from 3c into 214 with the stein hit keeping them airborne: 3c > 214d > }D{ > Walk Back > 6c > SoD~ > 6b > 66~6a > j.2c > j.5d > 2b > 5c > 2c > j.2c = 4747
And more.
