Here is my idea for a Luke hero. I will explain my reasoning later.
8/7 blue/gold hero
Heal a hero in play. If a hero would be discarded return hero to
territory instead. No heroes can be poisoned. May band with Paul.
Identifiers: Physician
Reasoning: Since he was a physician, he needed to incorporate protection without being broken. Notice, that his ability, while powerful, can be negated. His band with Paul can be easily stopped. Plus he can be converted and captured. Not to mention the fact that if he banded with Paul, (Missionary travels with Paul we find in acts.) no way do they get initative. So their combined power is limited. what do you guys think?
