The Six Samurai - Yaichi #SDWA-EN006

WaterMonster

Once per turn: You can target 1 Set Spell/Trap Card; destroy that target. You must control another "Six Samurai" monster with a different name to activate and to resolve this effect. This monster cannot declare an attack during the turn this effect is used. If this card would be destroyed, you can destroy another face-up "Six Samurai" monster you control instead.
