Instructions
Build your main deck; you can change or edit it at any time if your game strategy changes. To summon Exodia, you will need to include all five pieces in your deck: you need to have both arms and legs, as well as the "Exodia the Forbidden One" card in your deck.
Play through the game's story mode or link your Game Boy Advance with other players to test your main deck.
Use cards that allow you to summon cards from your deck and graveyard; this will increase your chances of being able to summon Exodia during a duel.
Play Spell and Trap cards that allow you to draw extra cards. The more cards you are able to draw, the better your chances of obtaining all five pieces of Exodia in your hand.
