SIDE DECK CHOICES, PART 1 The purpose of your Side Deck is to allow you to exchange cards in your Deck to deal with the strengths and weaknesses of the opponent's Deck, after the first Duel in a Match. If the opponent has a Deck with many Effect Monsters that have an effect that activates when the monster is destroyed and sent to the Graveyard, or if the opponent likes to Special Summon monsters from the Graveyard, like in a Zombie Deck, "The End of Anubis" is a great card to take from your Side Deck. This Level 6 monster negates any effect that targets a card in the Graveyard, or that activates in the Graveyard. This will stop your opponent from getting any use out of cards like "Manticore of Darkness" or "Soul Resurrection". - click here for another Dueling Tip.
