[+1]: Reveal cards from the top of your library until you reveal an artifact card. Put that card into your hand and the rest on the bottom of your library in a random order.
[−3]: Target opponent loses life equal to the number of artifacts you control.
[−8]: Gain control of all artifacts and creatures target opponent controls.
If you don’t have an artifact card in your library while resolving Tezzeret’s first ability, you’ll reveal your library and then randomize it.
The effect of Tezzeret’s third ability lasts indefinitely.
