To further the scaling chain for Taskmaster.
Bullseye is another street leveler in Marvel. He's so accurate that literally anything thrown by him can be deadly (and he's not superhuman (for Marvel, anyway)). He can slit a throat with a playing card, spit his own tooth with enough accuracy and precision to penetrate a human skull, toss a paper airplane several buildings away, kill
Elektra easily, and throw a toothpick with enough force to kill someone through a window 100 meters away.
Black Panther says that his skill is on the level of your everyday Wakandan street performer after a Super Skrull with Bullseye's skillset (and much much more) tries to throw something at him and he easily catches it.
And once again, BP < Cap < Taskmaster.
