It's a fun idea, but there's no way I would take it in its current state. 11 of each resource is just too expensive, even with the Destruction keyword. Obviously this card works best against expensive cards. Yet, even against the most expensive cards in the game, it's only so-so. And furthermore, your chances of countering those cards is pretty low since:
a) The chances that your opponent happens to have one of them in his deck && he draws it && he's willing to play it knowing that you have the Ring in your hand, are pretty low.
b) Such expensive cards as Dragon Squadron, Pyramids, All-Element Attack, Orc Regiment, Spectral Dragon, etc. tend to be game winners, so you won't have a chance to counter them since you'll have lost.
c) Even if you do survive a card like Dragon Squadron or Pyramids, chances are it left your opponent with few of the corresponding resource. Do you really want to pay 33 resources to lower one or two of your opponent's facilities by one and make him lose half a dozen resources?
So yeah. I suggest it be made much cheaper.
