Recall makes Tracer an almost impossible kill to find when she is using this ability properly. Rewind healing her to 3 seconds before, as well as relocating her to that position, Tracer will be hard to finish off. Add the benefit that Rewind cleanses debuffs, removes another Tracers Pulse Bomb, or can be used to dodge stuns as long as the animation finishes. Because Rewind does have a 12 second cooldown, forcing usage of this will be critical to secure the kill on her. Pulse Bomb, when stuck by it, will instant kill most heroes because it does 400 damage. There is not much way to avoid being killed by this ability if Tracer wants to stick you. If we get stuck, or a teammate does, remember to quickly spread out and negate its aoe damage (which its Area of effect is pretty limited to begin with).
