I was apparently summoned,
bit surprised considering I’m not even a supporter but let’s see for now
Yor’s fighting style is to essentially stab her adversaries in the heart, chin, brain, and other vital organs… and sometimes kick at them whilst mixing in her knowledge of pressure points to quickly incapacitate them or increase the lethality of her attacks, however Yoon’s regeneration pretty much neg one aspect of her fighting style according to the description. Well, don't worry; her weapons contain poison potent enough to kill an elephant… until I discovered that the guy also has some degree of poison manipulation resistance; I'm not sure how strong, but I'm assuming it's sufficient to counter Yor's poison. Therefore, Yor's fighting style is hampered by the Regeneration unless she could hit and destroy that marble in Yoon's stomach (which she might as she tend to also
stab at the stomach), but actually succeeding in that will be quite the feat in and of itself considering the skill and abilities Yoon has such as AD that can improve his strength, speed and skill while fighting on top of his attack speed buffs.
His stamina is more impressive than Yor and can probably outlast her if it comes to it I suppose
Invisibility probably won’t be as effective to Yor given her Enhanced Senses, Instinctive Reaction and Extrasensory Perception.
Analytical Prediction is going to be a pain for Yor to handle, though she does have her own AP in a way via her ability to sense a person’s malice and even when the person is
skilled enough to hide it until the very moment he attack, she could still dodge his weapon,
a weapon she even stated to have no experience with, and protect two people at the same time without even looking. So, Yoon’s Resistance to AP shouldn’t be effective I think since Yor isn’t reading his move to predict his attacks but more sensing his malice to know where and when the attack is coming.
Haven’t fully examine/read Yoon’s profile to write up more, but at a glance, I can say Yor is going to have a bad day to say the least against this guy
