Rulings
- You can activate Chain Destruction when you or your opponent Summons the monster.
- If you activate Chain Destruction when a Fusion Monster is Summoned, monsters in the Extra Deck with the same name as the Summoned monster are destroyed.
- Chain Destruction targets the Summoned monster.
- If an effect is chained that increases the Summoned monster's ATK above 2000 or removes it from the field, Chain Destruction's effect is still applied.
