New Twist on an established stall strategy.
Use 'Astral Kuriboh' or 'Right-Hand Shark' to set up a 'Number 59: Crooked Cook' and ensure he's the only card on the field.
As soon as you have 'Creature Swap' or 'Mystic Box' in the clear use your remaining resources to summon 'Bahamut Shark' and cheat 'Number 30 Acid Golem of Destruction' onto your side of the field to use as the card sent to your opponent. This locks your opponent out of special summoning and burns for 2000 each turn, while keeping your field clear.
Whether burn damage, 'Final Countdown', or Exodia victory is soon to follow.
