الساموراي الخالد

While this card is face-up on the field, it cannot be Tributed, except for the Tribute Summon of a Warrior-Type monster. During your Standby Phase, if this card is in your Graveyard and all the monsters in your Graveyard are Warrior-Type: You can Special Summon this card. You must also control no monsters to activate and to resolve this effect.
