I didn't want to post the correct way to j.214C cause, well, i need some good stuff for later right?
best set up for that combo is anti air 2C
2C > hjc > j.B > jc > j.C > 214C > j.C > 2C > hjc > 2C
but if they have to be close, so if there not
2C > hjc > j.2C > air dash > j.C > j.214C > j.B > land > 2C > hjc > j.2C > airdash > j.2C
after moves like j.2C and 214B hyper jump IAD, it moves very fast and in most case can get you to the ground before wake up shory, but you have to do it fast.
Edit: sorry looks like i missed a couple of things, um 2B most reaches farther, so i don't take the chance of a wiff and i just 2B, but if you can judge that consistently, go for it.
forward hop cancel hotaru > land > forward hop cancel tsubaki > hotaru > land > forward hop cancel tsubaki > hotaru > land and i think you get it
but my favorite mugen corner combo is,
forward hop cancel hotaru > 6C > shippu > 623A > 6C > shippu > 623A > 6C > shippu > 41236C
