Generally ,you need to have the skill shot inside you to play ezreal.Spam as much as you can with W as it passes through minions.Make sure u will strike your opponent with E.that will give you a huge advantage. especially as you dodge some of their skillshots.Try to avoid fighting when you are low if there are chances of losin.Back with E(striking your opponent) and use ult to secure the kill.Dont hesitate to use ults as it has low cd and it decreases even more by hitting creeps/champs with q.

PROS OF EZREAL

*can deal tons of damage at short amount of time

*he is gay therefore not racist

CONS OF EZREAl
-he is REALLY vulnerable
-try to avoid being silenced at any cost
-he is gay so he likes getting damage so try to snip kills and avoid long fights
