What is a trap card?

Answer 1

A trap card in the Yu-Gi-Oh trading card game is a great way to change the out come of a duel. They are the pink cards. For example kunai with chain. To use a trap card you have to place it from your hand into one of the spell/trap card zones. You can place as many as you want per turn, but only up to five traps can be on your side of the field at any time. You can usually use traps during your opponents turn, for example, if you placed the card Mirror Force in a trap card zone during your turn, and your opponent tries to attack one of your monsters, you can reveal your Mirror Force trap card to negate the attack and destroy all of your opponent's monsters! As said before, you can usually only activate a trap card on your opponent's turn. If you set a trap card you can use it once your turn ends and your opponent does what is necessary to activate it. When you finish using the trap card it goes into your Graveyard. You can use as many traps as you want during a round, just like you can place as many you want during a round. Unlike Spell cards, trap cards must be set down before you can use them. You cannot use them directly from your hand.
