Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
While "Umi" is on the field, each player can only control 1 face-up non-WATER monster. (If a player controls 2 or more, they must send some to the GY so they only control 1.) During your Main Phase: You can add from your Deck to your hand 1 "Umi", 1 "Kairyu-Shin" Spell/Trap, or 1 "Sea Stealth" Spell/Trap. You can only use this effect of "Ocean Dragon Lord - Kairyu-Shin" once per turn.
