Judgment of Anubis (LCJW-EN135) [Legendary Collection 4: Joey's World]

When your opponent activates a Spell Card that would destroy a Spell/Trap Card(s) on the field: Discard 1 card; negate the activation, and if you do, destroy it, then you can destroy 1 face-up monster your opponent controls, and if you do that, inflict damage to your opponent equal to the destroyed monster's ATK on the field.
