There is a YouTube video that shows a gameplay of a level 4 Cosmic treadmill equipped on DCEU Superman and he didn't manage to do 2billion damage.... And it makes sense.. because incoming damage usually is a support thing.. you apply incoming damage with your support character and then you tag in the damage dealer with beta club or Fahren knife and then you do the damage... But with the cosmic treadmill, the damage dealer is the one who applies incoming damage and that incoming damage multiplies your attack....and that's it... But with the gemstone, losso of truth, hand of zatanna, those artifacts are equipped by the support characters ,you apply the stack, you tag out ,you tag in your damage dealer with beta Club or Fahren knife and then the incoming damage is multiplying the OP artifacts...not just your damage dealer's attack like Cosmic Treadmill does....

Just search on YouTube "injustice 2 mobile Cosmic Treadmill" and see it for yourself...
