Simple mixup:
236a 214a 236a/b
If you did the b version as an ender and it hit then combo with 5B 5C -> whatever (For reasons unknown, it becomes much easier to combo into 5B when the 214a hits)
If you did the a version as an ender and it hit, then it's a knock down and commence oki
If you did 214a/b as an ender, it pushes you back, but not super far hard. Hard to punish, don't be too optimistic
If they block any of the 2 versions, then you get too far back for many things, but you lose all pressure and situation resets.
If you went ahead and did the c version as ender anyways and it got blocked, LOL EAT FREE COMBO
