Kairyu-Shin - Leviathan

Level 5 WATER

Sea Serpent / Effect

You can only use the effect of this card once per turn.

While "Umi" is on the field, each player can only control 1 face-up non-WATER monster. (If a player controls 2 or more face-up non-WATER monsters, they must send some to the GY so they control no more than 1 non-WATER monster.)

During your Main Phase: You can add 1 "Umi" or "Kairyu-Shin" Spell/Trap or "Sea Stealth" Spell/Trap from your Deck to your hand.
