Venser was an artificer that was discovered by Teferi, as well as many other planeswalkers, and was recognized for what was similar to a planeswalker's spark. He built the ambulator which allowed him to teleport from place to place, but not plane to plane,until he realized his own powers with the help of Teferi and friends. In the Scars of Mirrodin series he teams up with Koth the Hammer and Elspeth Tirel to save Mirrodin.
