USE CARDS TO YOUR ADVANTAGE Some cards have effects that treat both players equally. "Heavy Storm" destroys all Spell and Trap Cards on both players' sides of the field. "Creature Swap" switches control of two monsters between the players. You make these cards work to your advantage by activating them in the best situations. Save "Heavy Storm" for a time like when your opponent has many Spell and Trap Cards on the field and you have none. If your opponent only has one monster on the field, and it has a high ATK, Summon a monster with a low ATK, then activate "Creature Swap". Then you just traded a small monster for a powerful one. Using these cards in this way will make it so you get the better part of the deal. - click here for another Dueling Tip.
