for early game i recommend farming till ur lvl 6 or when u get a gank, after u get BT or TriForce play aggressive.

for runes if u play aggressive take armor and magic pen/resist runes because ezreal is squishy than other adc's, if u play safe i recommend taking the same runes like mine or similar ones to it

for masteries as u can see i take 23/7/0 because i dont like to take barrier alot on ez cuz hes the safest or almost the safest adc of all times

for items build ur core items for early till mid game and for late look at ur enemy team composition and items and take stuff that counters their CC, heavy AP,heavy AD, etc....

for skills max ur mystic shot 1st then ur arcane shift 2nd and lastly ur essence flux, if u want the essence flux debuff then take it at lvl 4.

for ezreal take any spell but i pref ignite cuz hes already the safest adc and ignite matches with ez alot so as barrier, but barrier is a safe spell so i dont recommend/pref it on him

if ur playing against a champion that counters u like draven for example just play safe and farm till u get a gank or so and try to poke him so u can burst him down but if ur playing against a champ u counter like ashe for example then play aggressive without fear but DONT PUSH UR LANE and watch our for enemy ganks.

Pros cons
- very good burst and poke - countered easily
- high range on mystic shot - his DMG falls off a little bit late game
- mobile adc - if u miss ur skillshots then ur doing nothing
- his ultimate is very usefull
- safe adc
- very good at countering
- one of the best escape champs

for teamwork keep hitting and poking from behind and when the enemy team are next to each other use trueshot barrage immediately before they split appart.

for early game focus alot on farming and poking the enemy
