Question

It has recently become clear that you can “overpay” for cards, but you cannot be considered to have “paid” more toward a card’s cost than its printed cost value. The Power of Leadership reads “double de number of resources this cards generates while PAYING for a leadership card”. If I play Ant-Man (Hank Pym, with 0 cost) with The power of Leadership, how many resources does that card generate? Am I paying or am I overpaying?
