I'm not very knowledgeable on MHA, so correct me if I'm wrong, but Deku's range advantage might not matter much. According to Tsukishima's profile, he has invulnerability to anything that doesn't attack at the soul, and to my knowledge, the only thing in Deku's arsenal that attacks souls is his punches. So Deku being able to create big ass shockwaves that are thousands of kilometers long won't be doing much for him here.
Also, if Tsukishima uses his speed amps, he'll be completely undetectable to Deku's enhanced senses and danger sense. So what stops him from blitzing with Bringer Light?
