Forum:Flip face down and equip cards

I know that you can't use equip cards on facedown monsters, but what happens if you equip an equip card on a face up monster that has an effect of flipping back into facedown,(like, Gaurdian spinx, Moai interseptor cannons, Gaurdian statue, ect) then you flip it facedown due to its effect. What happens? Does the equip card get destroyed or not? 91.106.8.226 (talk) 23:23, March 6, 2011 (UTC)
