Destroy target creature. You may search your library and/or graveyard for a card named Tezzeret, Master of Metal, reveal it, and put it into your hand. If you search your library this way, shuffle it.
Card Rulings
2/9/2017 If the target creature becomes an illegal target for Tezzeret’s Betrayal, the spell won’t resolve and none of its effects will happen. You won’t search for Tezzeret, Master of Metal.
Still doesn't make the new Tezz "good"; just on board more consistently.
I run a Chandra EDH deck and at first when I saw the Chandra Tutor I am like "WOOH!" And then I realize "Wait. I can only tutor a single specific chandra card...crud. Well Guess I am just going to have to use Gamble instead."
Like if it were "Search your library and graveyard for a Chandra card." I bet it would actually see some use. As you can start having a toolbox of specific planeswalkers like Chandra or Gideon or Jace or Liliana or whatever else.
