This reprint from Mirrodin Besieged has solid potential as a sideboard against aggro decks in standard, and it will see some play in commander format as well.
The price still holds up pretty well because of its popularity and an overall lack of supply. The current price is the perfect fit for this new reprint, while the original print remains at about $15.
Usually, old cards have the potential to remain valuable for a long time, so this is a pretty safe investment. There are no prices for the alternate art yet, but they should be around $10 each.
