My theory on brass rise

I've seen alot of people use slasher claws with brass lately. This could have involved the raise on brass it was random and unexpected but there must be a reason. This could be one of the reasons if not is the reason when things are great in combos it starts rising for example, Scythe (rising), grenade (rising), trident (getting better token offers) Gravity gun, (rising) let me know your opinions
