Yuzus 421x move teleports you, on knockdown a good way to catch your opponent on wake up is to teleport and do 6c (works miracles on angry people) I recommend 421a and 421b for consistency, but 421c is really good at getting some random damage in, but can be very janky. 421b and c are also good options to just say ♥♥♥♥ you to people playing at range

236b and 236a have dummy thicc range so just abuse that to you advantage, swap which one you use based on what you think they are gonna do, but a good combo is 236b>236a> 421c>214b>2c>236abac

yuzu has bad defense options so throw out 214c to get out and then press d and release d to do a D cancel so you can actually be less negative on recovery, try not to use this to often though as a simple 2a or well timed 2c can get you out if combined with shield

the whole point of these games is to enjoy your character and have fun, losing is just a way to understand what you need to learn, labbing her is not enough, play people and lose until you can land those combos you've labbed for 60 hours.

If you are not having fun with yuzu, maybe you should switch characters, its okay to not play the samurai lady because she doesn't fit your play style. or if its not her, maybe you should just take a break and try another game (guilty gear xrd rev2, and blazblue are my go to's when I'm burnt out on uni)

now go out there and kick some ass
