Starter decks Depending on the name used at the start of the game, you will get a different type of starter deck. Try names such as "Konami", "Rod", or "Puzzle".
Easy Win
Once you have the map edit mode enabled, edit the map to what ever preferences you want. Make sure you put labyrinth terrain all the way arround where your opponents deck leader square. Then when you fight using your map, your opponent will not be able to play any cards. So you win on the first turn. Use this only for the reincarnate ability. Because you are unable to get cards from the graveyard slots, it is basically useless unless you want the reincarnate ability.
