Trap Card

Trap Cards are designed to either make things difficult for your opponent, or easier for you, in a Duel.

Let's take two Examples. Spellbinding Circle and Jar of Greed.

Spellbinding Circle stops your opponent sttacking, and can often be a game turning point, if you have a more powerful monster waiting in the wings to unleash. As you can see, unless your opponent counters this card with another Trap Card, suck as Solemn Judgement or Seven Tools of the Bandit, this can prove quite frustrating for your opponent.

Jar of Greed, on the other hand, allows you to draw 1 Card from your Deck outside of the Draw Phase. This can be of great help when dueling, especially if you are reduced to Top-Decking.
