Guilty Gear Strive - I-No Corner Combo 2 Electric Boogaloo

You have to be super fast on the 22RC otherwise close slash won't connect in time. It's easier to go straight into 6HS but then you lose the final wall splat and break. May not be more optimal than STBT routes, but HCL does more damage than S-Stroke so it's definitely a more optimal starter if you can confirm into it.
