STOPPING SPELL CARDS Spell Cards are a major part of the game, so you can expect most opponents to play with them. If you play with a Deck with mostly Trap Cards, you will surprise your opponent, and can use the following Trap Cards that will hinder your competition's ability to use Spells. "Curse of Darkness" deals 1000 points of damage to a player every time they activate a Spell Card. This will make the opponent think twice before activating one. "Cursed Seal of the Forbidden Spell" can negate a Spell Card if they decide to activate one, and it prevents them from activating any other copies of that Spell Card for the rest of the Duel. If "Curse of Darkness" is on the field, they will still take 1000 damage too. You are required to discard 1 Spell Card to activate "Cursed Seal of the Forbidden Spell", so you should include a couple of your strongest Spell Cards in your Deck. - click here for another Dueling Tip.
