Both cards are straight out of the pack, have not been played.

What I value them at:

Foil Abrupt Decay: $35-$45 (per completed Ebay listings)
Foil Overgrown Tomb $25-$35 (per completed Ebay listings)
I am willing to negotiate a bit as well.

A couple caveats: Although I have her on my wishlist, Vraska is not a current high priority.
Any offer that does not include a non-foil version of the card wanted will not be considered.

I also have a bunch of other RtR stuff for trade and my wish list has a ton of stuff. I will try to check this thread throughout the day but am at work so may not get a chance to.

Foil Tomb is traded.

Still looking for offers for the foil Abrupt Decay!

Will listen to all reasonable offers!

Abrupt Decay is now traded.

Cheers!
