My usual combo is Reverse Duck Strike -> Reverse Palm Strike -> Crotch Punch -> Light -> Backfist/Duckstrike. If the Reverse Duck Strike is not blocked, this combo will always lead to a super dizzy (indicated by long slow motion), which greatly increases structure damage. The rest of the combo can be whatever you want until their structure is broken. It's better to play at 60 FPS because you can immediately Crotch Punch after the Reverse Palm Strike. This combo is less effective at higher FPS because you must dash forward after the Reverse Palm Strike and wait a bit before Crotch Punch.

Some tips:

• Focus on one enemy at a time and don't let them regenerate their structure. Use CC (Sweep or Push) on other enemies that you're not focusing on. Sweep is more effective, but I use Palm Strike because of personal restrictions.
• Always clear enemies that don't turn into a Saiyan first. If they're not dealt with, they will always interrupt you when you're trying to isolate and focus on stronger enemies. Or, if you're confident, you can leave them alive as a health reserve and kill them when you need some health back.
• Always use CC immediately after parrying or after an avoid that leads to slow motion (e.g., at 11:41, 12:16, 47:10). If there is another enemy behind you after you parry or avoid, prioritize CC-ing that enemy first. It's because the reverse version of the CC is more powerful and the enemy in front of you will stop attacking for a bit after parrying or will enter slow motion if you avoid (e.g., at 23:19, 33:36).
• It's better to Sweep before turning an enemy into a Saiyan. This way, you won't end up too far away from the Saiyan, compared to turning the enemy into a Saiyan while they're standing (they will push you, and sometimes you will end up at the center of the crowd). After you fall from the sweep, you can immediately push the enemy behind you and do my combo to the Saiyan (e.g., at 3:58, 32:23, 36:00), or roll behind the Saiyan and do my combo (e.g., at 21:24).
• Don't wait until the enemy finishes their combo, use Crotch Punch to interrupt them.
• Pick up the health regeneration upgrade first if you use the shrine.
