I'll trade for any Foil Shocks other than Hallowed Fountains, but priority would go to some combination of the following:

• 2x Foil Breeding Pool
• 1x Foil Godless Shrine
• 2x Foil Sacred Foundry
• 2x Foil Blood Crypt
• 2x Foil Overgrown Tomb

I don't really play Standard, but would also consider looking at Modern Masters cards for the Foil Voice.

Start up a trade if you're interested in making a deal.
