Skill:
There are many items for Ezreal that you can combine, basically you still have to get BF Sword, Wooden Bow, Sparring Gloves, Oversized Stick, Tears, Giant's Belt. Ezreal only needs items like Infinity Edge, Giant Slayer, Rageblade, Infinity Edge, Blue Bow, Deathblade, Piercing Mace, Hand of Justice, Blue Charm, Spear of Shojin. With items that support faster casting like Blue Charm, Rageblade or Spear of Shojin, you should prioritize if you have 4 or more Big Hands and Big Faces in the team.
All 4 Big Hands and Big Faces can carry items for Ezreal, with HeartSteel only Aphelios is suitable. So consider throwing items to champions that you think can carry items for Ezreal and deal good damage early in the game.
There will be plenty of damage in this team, Ezreal will need a lot of support items like Rageblade, Blue Buff, Spear of Shojin to cast skills faster. The trio of Corki, Miss Fortune, Kai'Sa will be the damage support champions in the early game. Corki or Kai'Sa can help carry items for Ezreal because these are 2 champions that deal quite good damage in the early game.
Or you switch to 5 HeartSteel and have 3 Big Hands Big Face, of course 1 Big Hands Big Face will be a Superstar and if you can hold out until the end of the game to catch Superstar Ezreal then hold out, he will deal more damage if he is a Superstar.
You raise HeartSteel to get hearts to exchange for rewards, so you can raise it early in the game to accumulate gold to 8 quickly to get Ezreal. This lineup's damage will come from Ezreal, Jhin, Miss Fortune, Aphelios and Kayn and the tank will depend on the remaining generals. So the equipment will be spread out to many generals, if you see a general with more, throw it to that general first.
Or choose to raise up to 7 HeartSteel and can increase to 9 if you press. You will have more generals and level them up to 3 stars faster, on the condition that you will have to level up to 8 quickly to get Kayn. And will have to eat a losing streak to get the gift. But don't lose too much blood.
The generals will level up faster, then you don't need to spend money on other generals, just focus on taking care of Ezreal without worrying about the force being thin. At that time, there are many items so you can distribute to all generals.
Ezreal may not be a late game pick because he has to compete with Kayn and Jhin, but if you see him popping up a lot at level 8, don't ignore him.
