Skred Red has been a deck in Modern for a while, but winning a Grand Prix certainly made the deck more visible. When I was an FNM warrior you could find Snow-Covered Mountains in the community land boxes at your LGS pretty frequently, though today the card is in the $2-3 range.

I would definitely not be looking to pickup Snow-Covered Mountains at this time, though there is no shortage of these in the bulk of established players. I'm sure many of you have a small stack that you could locate without much difficulty.

Both the Coldsnap and Ice Age versions are buylisting for over a dollar currently, which is always nice for a card that was once very easy to come by. This is also a nice one to stick in your trade binder to round out trades. Given that Skred Red plays double-digit copies of the card, the demand is relatively high as compared to players who actually need the card, which is good for the card's long-term price.
