There are many defensive and offensive oriented option selects and techniques that when taken advantage of become extremely powerful in dealing with a variety of situations. Described are the most commonly used techniques along with how to perform them and the strengths and weaknesses of each one.
Used to deal with AB from the opponent
The input is A > A or B > AB (Standing or crouching attacks does not matter)
On hit or block you will get A > B
If the opponent uses AB you will get A > AB
With the proper resources and reactions, the opponent can punish the clash attempt with Ranbu, Combo Blast, or Trump Card
If the opponent throws, you will throw tech
If the opponent goes for 4AB, Trump will activate
If the opponent attacks, you will pushblock
You want to delay the input as long as possible because it will lose against delayed throw attempts
This OS costs a Trump Card so be weary when using it
Plink B then C to perform, if both buttons are pressed at the same time due to button priority you will get C instead. Effect is similar to 4AC Throw OS, but will also catch opponents using jump to throw bait
In the case of 4AB clashing against 5B, you can Trump, AB, Blast, etc. on reaction
Very effective for characters with an anti-air 5B
Loses to frame traps
An alternative to the Ranbu OS mainly used for punishing reversal backdash
The input is any jump normal > 5AB
This will work for most 5ABs that have good horizontal range
For some characters with multi-hitting AB attacks, this OS can also be used against reversal Power Blast
Another variation of the Safe Jump OS, mainly used for punishing reversal Power Blast without 2 meter
The input is any jump normal > 5AC
Most effective when used with Red Trump Cards, but it's also possible to use Blue Trump Cards then 5AB
Does not work for Kirino
Slightly more riskier because if the opponent backdashes, depending on your character the Trump Card can whiff
Used to deal with almost every reversal option in the game
The input is any jump normal > 63214BC
This OS does not work for any character with a j.214X attack
Against reversal AB the safe jump will clash and you will block the attack
Against reversal Power Blast, Red Trump Card, or backdash, you will get Ranbu (in the case of a Blue Trump Card the jump in will whiff)
An overall very safe OS, but costs 2 meter
A technique where 5A is timed so that you will block against jump in attacks, and in the case where a jump in is not used (ie. double jump, empty jump low/throw etc.) 5A will come out
Loses to delayed jump in attacks (ie. Asuna j.236C, Kirito j.236X, etc) and moves with invuln upon landing
A technique where jump, then immediately crouch, is timed right when the opponent would throw
The input is 171
If the opponent throws, you will jump
If the opponent attacks, you will block
It is also possible to input 17BC1
If you mis-time the fuzzy jump and the opponent throws, you will tech the throw
If you do not mis-time the fuzzy jump you will get 7j.C
If the opponent attacks you will pushblock
Loses to staggers
A high risk/high return technique
A technique used to deal with multi-hit jump ins (Shana, Kirino, Yukina, characters in Trump State etc.)
Do not stand guard until right before you have to block the opponent's jump attack
If it is successful you will only have to block one jump attack, or the opponent's attack will whiff
Risky to attempt because if timed incorrectly you will eat a combo
A very specific technique that only applies against Selvaria's Trump Card
While blocking the attack, hold forward while using pushblock
instead of getting pushed backwards, you maintain your positioning allowing for an easy punish
