Blue Ezreal ADC

Why this build works
This is a "Blue Ezreal" build focused on ability spam and on-hit damage rather than pure crit. The mana stacking from Iceborn Gauntlet and Manamune lets you spam Q constantly for poke and wave clear, while Muramana's activation gives burst comparable to crit builds without needing as much gold invested in crit items. Blade of The Ruined King and Last Whisper keep your autos relevant in extended fights and against tanky enemies, so you're never a one dimensional poke bot, you can also duel and siege.

Order tips
Start Doran's Blade into an early boots or Long Sword depending on lane state. Rush Iceborn Gauntlet if you're facing lane pressure or need the slow to survive dives and ganks. Rush Manamune first if you're ahead in lane and want to snowball into Muramana faster for burst trading. Get Ionian Boots of Lucidity as soon as a recall allows, ideally by second or third back. Save Last Whisper for when the enemy team starts stacking armour, usually mid to late game.

Matchups
This build spikes hard once Muramana comes online, so it favours lanes where you can survive early all-ins and scale, think Caitlyn, Ashe, or Sivir on the other side where you can out-poke with Q. It struggles more into aggressive all-in ADCs like Draven or Tristana who punish you before your mana scaling kicks in, and into lanes with heavy poke supports like Zyra or Brand who can zone you off farm before you get your first item spike.
