- Use sea stealth trap and sea stealth spell to cheat out cards from the hand or GY.
- Sea stealth battle protection is not once per turn
- Fish sonar + sea stealth II gets you the floodgate if you play the normal salmon you can tribute summon
- Forbidden drip helps get the ice barrier in the grave if we brick
- Against a water deck just make toad and pray
- Electric jelly cannot negate traps. So if you think they have imperm just normal Ocean Dragon Lord - Kairyu-Shin (23931679) (assuming legendary ocean is up)
- If you can survive the turn and you banish the Ocean Dragon Lord - Kairyu-Shin (23931679) with Sea Stealth and Umi remains on the field you will force them to get rid of most of their board on the end phase.
- It is unlikely but possible to OTK if you get enough monsters and then activate mega fortress whale ability to direct attack. Be sure to kill your opponent with the vanilla salmon to maximize BM.
Have fun and stay dry!
