I'm assuming you you want to do "Gravity stuff>j.214D>5DD>236C>ect..."? I noticed the timing for it is pretty weird. I remember Ached telling me you need to delay 5DD to get the link. If it's litterally 214A>236C, then yeah, either you need to be in the corner or get a fatal off of 214A.
For 4B[2]>2DD>214A, I don't know what to tell you, I think I do the TK around the time 214A lands. I have to admit I have trouble with this combo myself at times, mainly getting the dashing 6A snd getting the 6C>236C. Just keep practicing.
If I'm wrong about something, let me know, I'm not a good Lambda player myself just yet. Any critique is welcome.
