Just pulled a 5* Longshot and looking for tips

Strategic

I got him at R3 right now and he seems fun. Synergizes well with some of my top champs too.
Now I can awaken him and take him to R5 and sig 104 so here's my question.
I currently run suicides and no MD although this guy gains power like crazy so MD is not needed at all!
So wandering any tips on using him? I'm a little confused by his sig ability though. Does it have a chance to nullify without using specials or what?
Also any tips are appreciated thanks.

I have a R5 unawakened. I love him. Don’t know about his sig ability, but it seems practical.

His best play style is parry, charge heavy to gain good karma, heavy, then repeat until you have 5 bad karma on the opponent and have pure of heart. Special 2 and watch them melt. Then keep applying bad karma to them while incinerated to keep the melting going.

On stun immune it’s a little different, but still easy. Dex 5 times to get pure of heart, wait for to run out to transfer the karma to them, try to get pure of heart again, and then special 2.
