Forum:Van'Dalgyon and Black horn of Heaven

During battle my opponent activated a trap that summons a monster to field, I activated Black Horn of Heaven and negated and destroyed, Van'D is summoned and is there an effect I can use? Black Horn only says negate the special summon and destroy, doesnt say negate the card that summons it. Shadowdragon5710 (talk • contribs) 05:37, August 31, 2011 (UTC)
