Target 1 face-up monster on the field; until the end of this turn, that target gains 400 ATK, but its effects are negated.
|Pack||Servant of Kings [SR]|
When the set monster you attack is flipped face-up you can activate Forbidden Chalice to negate it's effect.
Negate your monster's negative effect, so you can use them to their full potential.
Use Forbidden Chalice on Il Blud just before he is destroyed so that you can keep the monsters you revived with his effect.
Use Forbidden Chalice on Toon monster to protect them just before Toon World is destroyed.
Use Forbidden Chalice on Delg the Dark Monarch so that he can attack the turn he was summoned.
After giving away much of his attack, use Forbidden Chalice on Blue Flame Swordsman will replenish his attack.
Anki can attack directly using its effect, but it will only deal half of his attack. This can be "negated" by using Forbidden Chalice during damage step so that it will deal 3200 damage directly. But it is best not to battle a monster with Anki with Forbidden Chalice because he will not get his search effect.
