Cards are placed in a face-down deck, used from the hand after they are drawn, and discarded face-up.
You may use more than one card at once during your turn during the play cards phase.
You may draw a card from your deck when you lose a tower if you have cards left in your deck. If you do not have cards left in your deck then shuffle your discard pile and form a new deck.
After you take the first shot on your turn you can take an additional one.
Any time you take a shot this turn, you may choose to throw the Catapult Ammo from your hand instead of using the catapult.
You must still take the shot from the outside corner of your ground mat, and your hand may not go above the mat during the shot.
Any time you take a shot this turn, if the shot goes in a tower that is stacked on top of another tower take ALL the towers in that stack (not just the top one).
Instead of placing this card in the discard pile, place it face-up on any tower. The next shot that would go in this tower doesn't count - the player does not claim the tower for themselves. It is treated exactly as if the shot missed, and the ammo used for the shot is placed back in the supply pile.
Then, this card is placed face-up in the appropriate deck's discard pile. If the ammo bounces off the card, this also removes the Reinforced Roof.
Note: If Strong Ammo was played prior to the shot, they do not take any towers in the stack. In addition when stacking towers you may not stack new Castle Towers on top of Reinforced Roof.
