Shen, Eye of Twilight
How to play Shen
"From the shadows."
Shen wants to sit back and protect the point with a friend. Hold battlefields, especially with pairs of units. Tricks, strong units, and hidden cards win defensive fights.
Calm recasts the shield; Order pays for the wall. You are the other half of the Showdown pair — Zed races, you do not yield.
