midscreen: (2/5[A])2B5C6C launch jBBC falling jB, land > rejump, jBBC, land launch jBB release buster j214A (fastfall teleport) land > dash launch jBBCS
corner: same starter into launch jBBC falling jB, land > rejump, jBBC, land > rejump jBB release buster, j623A land > launch jBBCS
if you start with 2A or 5A and start charging yur lazur with A, it builds full charge.. if you're already charging you can start with jC,2B or just raw 2B.
corner loop from DHC to sougenmu is literally just (charging lazur)[launch > jB xx j236C]x3, launch jBB shoot lazur j623A land 623C
or if you want to add otg super you do a delayed j236C after you release the buster and super them soon as you land.
you can get all of that down in like 20 minutes or less, it really isn't that hard.
edit: p sure you can find a youtube video of every combo known in MvC3.
