Is your Spell card returned to hand or destroyed and sent the Graveyard when Reclamation is attached one of cards opponent plays Malevolent Catastrophe?

Here's how the interaction between Reclamation, Malevolent Catastrophe, and your Spell card works:

* Malevolent Catastrophe destroys all Spells on the field. This means your Spell card would be destroyed.

* Reclamation states: "Whenever a card you control would be destroyed, exile it instead." This effect applies to your Spell card.

* Outcome: Your Spell card would be exiled instead of being destroyed and sent to the graveyard.

Key Point: Reclamation's effect overrides the destruction effect of Malevolent Catastrophe, preventing your Spell card from going to the graveyard.
