There can only be 1 face-up "Earthbound Immortal" monster on the field. If there is no face-up Field Spell Card on the field destroy this card. Your opponent cannot select this card as an attack target. This card can attack your opponent directly. Once per turn, you can Tribute 1 monster, except this card, to select and take control of 1 face-up monster your opponent controls, until the End Phase.
