If you want to have a bunch of unblockable creatures, this deck is for you. Well... as long as your opponent(s) didn't have the same idea.
The Solitaire game states for this deck are not that instructive. Here is a small sample. The objective for this deck is to hit for lethal with Shadow, and that is a very simple premise. If your opponent doesn't have a fast deck or one that is prepared to fight a Shadow deck, this deck is a winner. Lucky for your opponents, Shadow creatures are Legacy creatures, and that means that they are typically not that great.
