SDI the fair and this combo won't work.
I suppose that that probably is the reason. Originally, I believed that the reason that players would get out of it earlier on was due to them being at mid to high percentage and the PSI magnet sending them too far, but SDI makes more sense. I was kind of in a hurry when I posted this, so I suppose that I should say that the combo
ideally repeats, but usually I get around two of these combo strings off, at early percentages, before I back off and switch to something else.
Also, I usually begin the combo with d-tilt, NOT DJC fair (I don't know why I wrote it the other way) as d-tilt seems like a safer approach than just Rambo jumping in with a fair. Doesn't change Boiko's point of SDI but at least you get a d-tilt, magnet, and fair out of it.
The PK Fire Cross-up idea that I had is pretty moot now that PK Fire neither lasts very long nor activates on shield in 3.5. Its not UTTERLY moot, but going in for a grab or aerial seems more free than trying to make it complicated with b-reversed PK fire cross-ups.
