Reversal Edge.
It builds a ton of meter, so after you've used a couple of REs, you have access to CE and SC as GTFO tools.
214B and backstep are also good ways of escaping pressure.
You can also go for fast interrupts like 6b8K, 66K, 6KB, 2A, etc, but Ivy will rarely win close range poking games against most of the cast.
Much thanks! 6b8K I didn't quite figure out though, didn't seem to do anything of note for me. Definitely many many moves to keep in mind.
