After launcher you press assist and then super jump.
A midscreen variant for drones assist would be…
cr. :l:, cr.
, st. :h:, :dp:
, cr.
, st. :h:, :qcf: :l:, dash, j.
, j.
, j. :h:, st.
and Drones call, :s:, super jump, j. :h:, :qcf: :s:, dash, j. :s:, BWA
There are cases where once you land from doing j. :h: :qcf: :s: you can actually do :qcf: :h:, the punch portion of the move will whiff and the rocket portion will connect, and since you recover faster from Closeline Rocket move pretty fast, you have time to connect cr. :h:, :qcf: :s:, but that sorta conditional and I rarely go for it, BUT ITS THERE! 
Nemesis’ optimal BnBs are as follows…
Midscreen
cr. :l:, cr.
, st. :h:, :dp:
, cr.
, st. :h:, :qcf: :l:, dash, j.
, j.
, j. :h:, st.
, :s:, air series, land, BWA. (721,800)
Corner
cr. :l:, cr.
, st. :h:, :dp:
, cr.
, st. :h:, slight delay before :s:, j.
, j.
, j. :h:, angled deadly reach, land, :s:, air series, BWA (702,700)
