The only time I use sword stance.
After the 33, 23ss, 11b1, 11b1, 11b1, 11b1, f21db2 combo when the opponent is cornered.
Then your SS armor F3 is fucking awesome at stuffing wakeups.
You can F3 NJ3 11b1, 11b1, 11b1, 11b1, f21db2 as a overhead starter.
or
B2Ls, MB Forward Tiara, 33, 23ss, 11b1, 11b1, 11b1, 11b1, f21db2 as a low starter mixup.
Also frame trapping with SS D1 and D3 in the corner.
I though the bash would be good a chip weapon but instant airpunch, instant airdivepunch, air down tiara is better
