I've played MTG on & off for over a decade, and want to reduce the volume of my collection by ebaying lots of cards. So far I've sold one complete set (Weatherlight) and I've listed (mostly unsuccessfully) individual cards. Am I better off selling as re-packs of certain colors, Commons X4, ... What have you found is the best way to whet interest on eBay?
You are best off posting cards in playsets (x4) but to be honest the most sought after cards are the ones that will sell, regardless of their rarity. The rest you can just sell in bulk.
though what has been previously stated is true, you can also use these older cards, like the ones before rarity was defined, as an incentive for others to buy a lot of yur cards
