Instructions
Start with Uria, Lord of Searing Flame; Hamon, Lord of Striking Thunder and Raviel, Lord of Phantoms. You only need one of each Sacred Beast.
Add spell cards like Rare Value, Ancient City-Rainbow Ruins, Crystal Promise, Crystal Beacon or Crystal Blessing. You need continuous spells to summon Hamon. Plan around 19 spell cards for your deck.
Put several non-tribute monsters cards that are fiend-type monsters like Archfiends, Giant Germs or Dark World Monsters in your deck. These cards allow you to summon Raviel. You may want to use DNA Surgery to turn Crystal Beasts into fiends. Your total tribute and non-tribute monsters should total 20 cards.
Include continuous trap cards to summon Uria. You may want to include Gravity Bind, Mask of Restrict, DNA Surgery, Mirror Force and Ring of Destruction.
Use Raviel as your aggressive attacker, Hamon as your main defender and Uria to keep the path clear from traps and spells.
