Tezzeret, Agent of Bolas (Retro Frame) - 1043 - (Secret Lair Drop Series)

Put 3 loyalty (use counters) on Tezzeret. Opponents can attack Tezzeret as though he were you. Any damage he suffers depletes that much loyalty. If Tezzeret has no loyalty, he abandons you.
Once during each of your turns, you may add or spend loyalty as indicated for the desired effect —
+1: Look at the top five cards of your library. You may reveal an artifact card from among them and put it into your hand. Rearrange the other and put them on the bottom of your library.
-1: Target artifact is now also a 5/5 creature. It retains its original abilities but now it can be enchanted, killed, and so forth as a creature.
-4: Target player loses life equal to twice the number of artifacts you control, and you gain that much life.
