The eBay online marketplace lets you sell your items at a fixed price or as an auction where buyers bid up the sales price
Speaking of prices, for each major MTG format, there are a variety of exceptionally powerful and expensive lands
Nevertheless, Fourth Edition has several MTG staple cards and mechanics in its rooster, including: An interesting selection of old-school counterspells: besides the counterspellest of them all, Counterspell, Fourth Edition includes two color hosers (Red Elemental Blast and Blue Elemental Blast) that do double-duty as removal, and enchantments like Lifeforce that work as counterspells at interrupt speed (what would nowadays be an instant)
It also allows you to then cast a card from your hand with a mana value of X or less for free, which means you get even more value
