the main reason why this works and why I made this build in the first place is because of how blitzcrank e, passive and w work with items like these, blitz e has a 200% ad ratio and when maxed it has a 5 second cooldown (without ability haste), which means that this can work really well with sheen giving you an auto reset that deals a lot of damage and knocks the enemy up on a short cooldown, w gives you a bunch of attack speed and movespeed for a long duration, so of course that works well with this build making it hard to run away from you and making you stack conqueror really fast. And finally, blitz passive scales with mana, which means that you get extra value out of items like manamune, which not only helps by giving you more mana and damage but it also makes your passive shield a lot stronger.
