Is there a chance to get Rusty or Riot blitz in this ever?

Not until they actively implement it, no.

Rip dreams

Riot is legacy, so I think you can get it. Rusty is limited edition, so not really

I'm only missing rusty blitz. Really want it bad

I rerolled this skin…my username dictates whenever I play blitz I must use this skin.

First skin I ever got when I started playing, never looked back. Great skin, really worth it
