If you use a spell or trap card that is not an infinite equip can your opponent activate fairy wind to destroy it?

No, your opponent cannot activate Fairy Wind to destroy a spell or trap card that is not an infinite equip.

Here's why:

* Fairy Wind's effect: Fairy Wind states, "Destroy 1 face-up Spell/Trap Card that is an Equip Card on the field."

* The key restriction: The card specifically targets Equip Cards only.

* Other spell/trap cards: This means regular spell/trap cards, including continuous spells/traps, counter traps, and quick-play spells/traps are not affected by Fairy Wind's effect.

Therefore, only Equip Cards are vulnerable to Fairy Wind's destruction effect.
