It actually DOES have an activation condition.

Normal Trap Card
[Requirement] You can activate when your opponent Special Summons a monster (1500 ATK or higher) face-up by shuffling 4 Normal Monsters from your Graveyard into your Deck.

Note: This card’s name includes a play on Magical and Quartet overlapping in Japanese. Magical Quartet Shock would also get it across.
