Smith is restricted in Open. For no reason. But it is. It should be legal in standard for crying out loud.
The shadow is decent in Open, but I found that the best deck in open includes 4 copies of
Saruman's Power and
Greed (timing so they don't kill each other), with one purpose in mind: Hose all those intricate condition based decks, infi Gandy, Fruit Loops, etc.
Greed knocks off Treebeard in Fruit Loops,
Saruman's Power knocks off, oh, everything else.
