if you have a life lead and mash phase projectiles literally dont hit u... even deadshot bullet barrage wont. its nuts. his jump 1 is extremely hard to AA for almost everyone bc its hit box extends down so quick. learn the walk/duck while stay focused on their forward dash. he can duck fate projectile from extremely far. try to read an orb.
dead shot, you can't dash after MB riffle blocked. after bounce shot u can. learn the frame data of the projectiles u are having issues with and what your options after block/duck are.
