so uhhhh can someone give me some tips of how to beat Ekko? Zed counters Ekko easily pre-6 but after Ekko reaches level 6, its the other way around. When he's low on health (like 10% left), I ult him and he just ults and then does the slow/stun combo on me. After that it's hard to kill him with Zhonya + his ult. How do I beat him?
You can outfarm and force him back several times. He will outscale eventually.
if he is that low just keep doing what you were doing. No need to waste ult when he will ult+Zhonya. Keep pokin with q and wq to force him to use ult zhonya then ult him or just kill him. Remember your passive so try to bait him in and w in to auto then q after auto and he will be dead or forced to use ult. Play the mind game if you have more hp and he is low. People tend to go on survival mode and think they have everything ready in case things go bad. You want to abuse that mind set.
tldr keep pokin till they waste their back up stuff then ult.
Basically what Vakosh and MLDzXnRRR said, just remember, Ekko's ult can only heal him a percentage of the damage he's taken in the last 4 seconds. Try to get him to waste his ult then ult where his time clone is, or when he gets back to lane (just ward so you dont get 2v1'd by him and his jungler though).
You should outpoke him pretty easily. It's pretty difficult to all in him without a QSS for the stun though, and for the love of god don't stand close enough for his R to damage you.
Zed counter ekko because zed with shadow leave and ekko do his w
just buy QSS to counter his cc
