Noriaki Kakyoin
Kakyoin allows for conversions off of Trish's "Crush!" reversal, as well as post-GHA combos. In addition, Kakyoin's duration and range make it easy to swap between Stand Off and Stand On during such confirms, enhancing her overall damage output while not being as dependent on HH Gauge usage. Kakyoin does present issues when it comes to confirms near walls (most notably during OTG relaunches with s.3H), but the benefits far outweigh the flaws.
Yukako Yamagishi
Yukako makes s.3H conversions possible anywhere, in addition to being far more consistent when near the wall than Kakyoin. Yukako doesn't possess as much range as Kakyoin, making it harder (or even impossible) to convert off of "Crush!", but the improved consistency in areas where Kakyoin falls flat make for a perfectly acceptable alternative.
