when it's your turn , the computer will pick a card for you. this goes into your hand along with 5 cards that are chosen for you at the start of the game. you can then choose to put a card from your hand into the battlefield. however, you cannot do anything with the card you have just put in the field until after you have had your go by pressing end. when it's the computer's turn you will notice the red X across the card you put in the field after the previous turn will disapear. if ythe computer attacks you you will be able to use the card you just put in to counterattack. but if you do, you will not ba able yo use the card on your next go, However, if you do onot counter attack, on your next go you will have the card free to attack or do whatever you want with it.
hope that clears things up a little.
cradfighters is really confusing at first but once you get used to it it's a beast of a game. definetely one of the NGP's best. <img src="graemlins/mrt2.gif" border="0" alt="[Mr T]" />
