Have a concept for a new game mode (cause Riot is thirsty for those)

tbh this game mode would be a huge undertaking, but i think it could be a lot of fun. It would be a game mode where you can buy special abilities on champions that have overpowered effects. an example that i can think of is like, for say 700 gold, Nidalee can buy a Spear with infinite range and no damage cap, but can only throw it once before it reverts back to her normal spear. Or maybe a potion with Yasuo where for 10 seconds his dash cooldown is only a damage cooldown, so he can continually dash through the same target (but only deal damage the first time). For Ahri it could be something where her charm has increased range and will pass through champions to hit multiple ones. For Ziggs it could be like an ultimate bouncing bomb, where if the ultimate doesnt hit any enemies, it recasts in front of itself up to 2 times. the main problem would be making 1 or more of these for every champion.
