Theodosia, Mad Mechanist

0: Whenever you cast an artifact spell, create 1 Mania Token. (Artifact: "tap,sac: 1 colorless mana for artifacts/assemble or crank a contraption.")
+2: Reveal an artifact from your hand or library. Target player takes damage equal to its CMC. Cackle maniacally: "target" becomes "each".
-8: Place an Artifact creature from your hand or library into play without paying its cost. Say "Gentlemen, BEHOLD!": gain Mania equal to its cost.
