# Action Point System Each card has a different Action point requirement which is similar to casting cost of a card in other basic card games. AP will auto generate each turn and give equally to both players in a combat. When a player chooses to play any card, AP will be deducted from that player’s AP pool. If that player does not have enough AP to pay for a card, that card can not be played unless that player chooses to remove some card he/she played previously from the action. AP will be actually reduced from the pool equal to the sum of AP cost printed on the cards he/she has played this turn after finalizing the action. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
