Shouldn't really stay in lane with 20% hp then. You can also cc him under turret before using zhonya. I mean, this champion has a 43% winrate for a reason lol.
his win rate is lower because of his high skill cap, not because the champion is lacking. and zed has trouble dealing with the current yasuo/tryn/jax gods who horribly outscale him and do have the abilities necessary to contend with him at level 6.
100 AD (long sword or two maybe cutlass even) vs a 900(if that) health AP enemy laner (well say level 6, after first back)
and forget auto harassment at this point, because if you look at zed funny hes going to press R.
now as for poke harassment, thats usually limited to just Q, of which you go oom and cant cast any more, but before that happens hes already healed it all thanks to how gross lifesteal is. so you go into Q again, but why? he healed it all, so now you have to 100-0 the assassin to do anything. so you combo him, shame that eats away all of your mana.
zed's Q is hitting for 130 damage (-25~30% if you have armor runes), every 6 seconds he can spam it indefinitely. so over the course of the next 5 minutes i HAVE to dodge up to 50 shurikens. and im allowed to get hit 3x before im in kill range, or maybe hes going for those W + E + Q's as well guaranteeing at least some damage on occasion.
so what we can say for sure, the only way to stay in lane against a zed is to play a sustain champion or a hard counter. or wait for zed to screw up (wow such great champion design, only way to win against it is for him to mess up!)
you dont beat zed in lane, you manage him and come out even if possible and wait for ganks. unless ofc you die under your own tower because pre 10 minutes (upwards of 15 if you're behind on farm dodging all those Q's) you dont have your zhonyas completed.
