Theology's power and toughness are equal to your devotion to all colors.
When Theology enters the battlefield and at the beginning of your upkeep, draw a card for each color to which your devotion is two or more, then discard that many cards less one.
See Challenge # 156.
Thank you Alex for "theology". Hopefully this fits the bill :)
Interesting! I wouldn't have expected a blue card after reading the name, but it makes sense when I think about it — theology is the study of religion, not the practice.
