You can combo this card with "Forgotten Temple of the Deep". Use the effect of "Temple" to protect your monster and then you can use this card to search for another monster.
Since this card is similar to "Fish Rain", you can activate "Fish Rain" first then chain it to this card. So, you can add a monster to your hand and Special Summon the same monster. Make sure you have at least 1 Fish, Sea Serpent, or Aqua-Type monster, so that you are able to use "Fish Rain".
