Ok guys so this is my first build. I always use this and every time i won game.
I know that i should explain here many thing but if u know ezreal and how to play ez u won't need to know more.
Only i can tell u that u should always look on the all line and look for low hp enemy champions, this can give u be feeded at early game.
And one more, keep ur Arcane shift(E) for escaping, dont spam it to much for Sheen item.
And in early fights dont use many time ur Essence Flux(W), its cost 2x more than Mystic Shoot(Q)
Better hit 2x times Q. I usualy use Essence Flux(W) for support, use it on ur friend and he will get faster speed atk (many ppl dont know about this), ofc u can use this at ur enemy if u fight 1vs1.
Use ulti if u know that u will shot all the enemy, if not keep it for last hit (maybe kinda nooby but better kill him than let them run away.
In teamplay always keep behind from ur friends
This will help u to more surviablity.
I think its all, have fun :)
comment my build and tell me ur opinion.
