- This card can be searched by "A Cat of Ill Omen", "The Despair Uranus", and "Citadel Whale".
- This card's first bulleted effect can be used to meet the activation condition for "Underworld Egg Clutch".
- This card's first bulleted effect forms a great combo with the last effect of "Elemental HERO Absolute Zero", since both of these effects can be repeatedly used.
- This card's first bulleted effect is useful for protecting "Tornado Wall", which is reliant on the presence of "Umi" to survive (which, incidentally, is what this card's first effect searches for).
- Regarding this card's second bulleted effect, "Cyber Shark", "Depth Shark", the "Dinomist" monsters (specifically "Dinomist Brachion"), "Dragon Ice", "Eagle Shark", "Fog King", "Mecha Sea Dragon Plesion", and "Panther Shark" are all Level 5+ WATER monsters can be easily Summoned from the hand without Tributing.
- For WATER Decks in general (which lack easy access to Level 5+ WATER monsters), the following cards can be included to allow easy access to those monsters (in order to make use of this card's second bulleted effect):
- "Aleister the Invoker" and "Invocation" (along with possibly "Magical Meltdown"), which grants access to "Invoked Cocytus".
- "Mask Change II", which grants access to "Masked HERO Vapor" and "Masked HERO Acid".
- "Instant Fusion", which grants access to various Level 5 WATER Fusion Monsters (most notably "Elemental HERO Mariner", "Elemental HERO Steam Healer", and "Sea Monster of Theseus"), which can be banished by this card's first bulleted effect to avoid being destroyed during the End Phase.
