Let's take a zoomed-in view of a few of Magic's "jinxed" items.
You may already know that certain drawback-laden, "jinxed" artifacts flavorfully curse their controllers, and initiate a game of Hot Potato as soon as they hit the board. For example, Jinxed Idol from Tempest is a creepy stone figurine that stings its bearer for 2 damage a turn. Give it away as soon as you can -- if only to stop seeing its ugly mug on your side of the table.
But did you know that Mirrodin's Jinxed Choker is actually a thin silver snake that slowly tightens its grip, increasing its turn-by-turn damage as the charge counters pile up?
