a new champion mechanic concept

a Champ that uses gold instead of mana for abilities the champ would be ranged passive would give gold q can be single target ranged attack that uses like 5 gold (ad) w can be aoe ranged splash damage that uses 10 gold (ad) e can be defensive ability such as shield that uses 15 gold (ap) r i have no idea what it could be but it would use like 100 gold (ad and ap)

now players would need to do money management which i think would be really interesting
