Dimir Terror is a tempo-control deck built around cheap interaction and large threats like Tolarian Terror and Gurmag Angler backed by Counterspell and Snuff Out. Journey to Nowhere gives you clean answers to their delve threats that dodge Snuff Out and Cast Down's sorcery-speed restrictions, while Sunlance picks off Sneaky Snacker and Murmuring Mystic. Cut Prismatic Strands since they have very little in the way of a wide attack that would trigger its fog effect, and trim Guardians' Pledge since you'll rarely resolve a pump spell through their counterspell suite. Your best route to victory is flooding the board with small fliers from Battle Screech and Militia Bugler chains to go wide over their removal, pressuring them before they can establish Tolarian Terror.
