Ezreal Counter Tips
If Ezreal uses his E(Arcane Shift) in order to iniciate a battle in a teamfights or equal match-up then you must focus him, since he has no other escape spell.
Staying behing minions will save your from Ezreal's Mystic Shot.
When doing teamfights, avoid staying in a line becase Ezreal's ulty is AOE skillshot.
If you play against him on mid, push him under his tower because he has a terrible wave clear and make sure he loses CS on every wave.
