The start of a new block for Magic: The Gathering
Shadowmoor is the start of a new setting, giving a unique twist to old favorites and introducing new places, creatures, and characters to the world of MagicTM.
Shadowmoor introduces new mechanics and a new card type.
Like to exploit weakness? Then grab the "Mortal Coil" deck! This deck focuses on tricks you can pull with -1/-1 counters. Of course, the most basic "trick" is simply to put them on your opponent's creatures, which Grim Poppet, Torture, and Incremental Blight do with ease. But you're cleverer than that!

The deck has lots of creatures with persist, like Gravelgill Axeshark. When one dies, if it didn't have a -1/-1 counter on it, it'll return to play with a -1/-1 counter. Then use Leech Bonder or Fate Transfer to move that -1/-1 counter to one of your opponent's creatures! Your opponent gets weaker, you get stronger, and persist is set to go again. Winning the game has never been so hilariously cruel.
