If the terracotta warrior were to use "Just Like You" on a wastrel model would it use the TN printed on the card or the reduced TN as a result of McCabe's Adventure Awaits. Since Adventure Awaits directly alters the actions TN it would be as if the printed value was lower and would effectively negate the stat penalty the warrior has when taking that action. Also, if that is how it works then enemy obeys targeting a wastrel model would also gain the benefit.
