Card Rulings
2/9/2017 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.
2/9/2017 The effect of Tezzeret’s third ability lasts indefinitely.
Will admit, though. The new PW deck Ajani definitely is crap. Also just realized this is the "weak and relatively harmless tezzeret". What the heck is the good tezz going to be like?
They only did 2 last time, so this isn't from a PW deck.
