Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is added from the Deck or GY to your hand by an effect of a WATER monster: You can reveal this card; look at your opponent's hand. If this card is Special Summoned: You can send the top card of your Deck to the GY, then target 1 Level 4 or lower WATER monster in your GY, except "Deep Sea Artisan"; Special Summon it, but negate its effects. You can only use each effect of "Deep Sea Artisan" once per turn.
