Dark Sanctuary





This card gains the following effect if "Dark Necrofear" exists in its controllers Graveyard:During each of your opponent's Battle  Phases, the controller of this card selects 1 monster on their opponent's side  of the field (You do not tell your opponent which monster you have selected.) If  that monster declares an attack during this turn, its ATK is negated and your  opponent takes damage equal to half of its ATK, then your Life Points are  increased by the same amount. During your Main Phase you must release 1 monster on your side of the field, if you do not this card is destroyed. As long as this card remains on the field you can use your empty Monster Card Zones as Spell  & Trap Card Zones.

Rulings

 * Even if Dark Necrofear is not in the graveyard, you must still tribute Monsters for it's maintenance Effect.
 * Even if Dark Necrofear is not in the graveyard, you can use your Monster Zones for Spells and Traps, as it is not the effect gained by Necrofear's Grave-time.
 * The effect of inflicting damage to the owner's lifepoints forms a chain of spell speed 2. If that monster is destroyed before it's attack is negated, the effect fizzles and you do not select a new target.
