Etir pool, continuous spell

You may only activate this spell when you have at least one "Warehouse Agent-Undead" on your side of the field. If "Warehouse Agent-Undead" is destroyed in battle, after calculating battle damage, return him to the field. When "Warehouse Agent-Undead" destroys a monster, remove it from play and place one "Thrall Token" (Dark:Zombie/Attk:1200/Def:900/3 Star) on your side of the field. Treat "Trall Token" as if its name were "Warehouse Agent-Undead". If there are no "Warehouse Agent-Undead" on your side of the field, destroy this card.
