The entire point of your post was that Gitaxian Probe is much better than Street Wraith, which is something I admitted many, many posts up.
Then, you began spouting off the differences between Probe and Street Wraith, repeating text I already made:
Compared to Street Wraith:
Its also a blue card, which means the card can be pitched to Force of Will. Its also an instant/sorcery meaning that you can flash it back on a resolved Yawg Will, or with a Jace/Snapcaster, and that it also triggers your Mentor and adds to your storm. Unlike Street Wraith, its hit by spheres, it can be countered and can't be eaten by an Ichorid.
But I already said:
If all you were trying to do was thin your deck, for whatever reason, and you didn't care at all about what your opponent was playing or hand in hand or seek to generate storm or tokens, etc then Street Wraith would be just as good.
In other words, I already made every point you made. Street Wraith sees no play, but Probe is heavily played. That's not in dispute.
