Aslla Piscu
"Only 1 "Earthbound Immortal" monster can be face-up on the field. When there is no Field Spell Card face-up on the field, this card is destroyed. Your opponent cannot select this card as an attack target. This card can attack your opponent directly. When this card is removed from the field, other than by its own effect, destroy all face-up monsters on your opponent's side of the field. Then inflict 800 damage to your opponent's Life Points for each monster that was destroyed by this effect."
Mystik Wok
Tribute 1 monster on your side of the field and select its ATK or DEF. Increase your Life Points by the same amount.
