This card works well with "Venom Swamp", as it guarantees your opponent's monsters will be significantly weakened by the time they are able to attack.
Use this card in a "Toon" Deck: most Toon monsters won't be affected by this card.
In a "Umi" Deck, you might use "The Legendary Fisherman" together with "A Legendary Ocean", due to the fact that he won't be affected by this card. In addition, "Fisherman" will never be targeted by an attack due to his effect.
You would also Summon "Deepsea Warrior" and "Mermaid Knight" in order to employ severe Beatdown ("Mermaid Knight" will be affected by either this card and "Legendary Ocean" but may attack twice)
