Michelangelo

Temples, theaters, & wonders produce 1 extra per happy face; you don't spend extra civil actions per wonder for wonder cards.

Interactions and clarifications
Only happy faces count. Unhappy faces (like in Communism or Kremlin) don't affect Michelangelo's effect.

Effects that increment the amount of happy faces (like St. Peter's Basilica) do improve the effect of Michelangelo.

Fun fact: This card combos insanely well with St. Peter's Basilica, giving you the ability to have monumental culture production. For example, with both a single Age A temple gives +3 culture per turn!
