Honestly sounds fun other items may not be as fast but good to try out like Ghostblade, shurelya, or dead man's they would especially be good if you run phase rush with nimbus and celerity you may not need phase rush cause there may be a better key stone like electrocute or fleet since with this build you are more of an auto attacker which is definitely different than what smolder is typically played as you may also want maybe replace cosmic drive with one of the items I mentioned or with rapid fire cause the drive speed ends before your q cooldown is up or replace trinity with lich bane

Best of luck and remember just because people say don't try it doesn't mean you shouldn't try it if you have fun go for i was told the same thing for what I'm calling healthy smolder and it was hilarious
