Champion with mechanics that interact with an in-game item.

These were just shower thoughts, dunno if anyone posted it here before but i figured it would be cool if we have a champion whose main mechanic revolves around an item. Basically you can either choose to rush the items and make your kit mid game strong or choose to postpone it which will make your kit scale into the late game. These can be done either through stat buffs or added effects to the champion's original abilities(kinda like Kayn Blue and Red). So you would have time marks, like if you buy it from 15 to 25 mins, you get the Mid Game Kit if you buy it 30 sth minutes above you get the Late Game Kit( these are just examples, the time marks need to be balanced ofc). Maybe you can buy the item for a cheaper price if you decide to rush it but the longer you postpone it , the more expensive it becomes but the more stats it gives.(tho i would prefer it to change the original abilities then just giving stats)

And i think the perfect item and champion for this would be Blade of The Ruined King and the majesty himself.
