Subject: [PATCH] - Added a way to define card-based AI priority for paying the
 Remove Counter cost. - Set the AI priority for Power Conduit to ANY to avoid
 the AI lagging heavily while looping through the cost and spamming the
 console with errors. - Currently the AI will use this card rather randomly.
 Consider improving or marking it as RemRandomDeck at the very least.
