- Swarm your field with Fish, Sea Serpent or Aqua-type monsters that can Special Summon themselves or other cards, like "Superancient Deepsea King Coelacanth",, "Aqua Spirit", "Sharksucker", "Treeborn Frog", "Deep Sea Diva", "Fishborg Blaster" (traditional format only), "Shark Cruiser", "Salvage Warrior" (with "Deep Sea Diva", "Geomancer of the Ice Barrier", "Dewdark of the Ice Barrier" or other level 3 and lower WATER-attribute Tuner monsters in your graveyard) etc. to inflict more damage to your opponent.
- Another idea is to activate "Water Hazard" while you control no monsters to gain an extra summon.
- Another method is to Special Summon a monster from the graveyard with "Surface".
- "Ultimate Offering" and "Double Summon" can provide extra Normal Summons.
- Better yet, "Salvage" to return WATER-attribute Fish, Sea Serpent or Aqua-type monsters from your graveyard to your hand.
- Frog monsters can easily swarm the field for use with this card.
- To create an OTK with this card, first summon any monster. Then, set "Scapegoat", 2 "Poseidon Wave"s and "DNA Surgery". Before your opponent attacks, activate "Scapegoat" and "DNA Surgery", changing all monsters you control into Fish, Sea Serpent, or Aqua-Type monsters. When your opponent attacks, activate the 2 Set "Poseidon Wave" to inflict 4000 points of damage × 2 = 8000 damage.
