What you want to do is get shadows out as fast as you can, especially within the first three turns. In the event that you encounter burn or shooter deck, quickly get out your clerics. When your opponent starts to build up on creaturees, your can take them out with your archers. Enchantments shouldn't be a problem because of all the Disenchants. The sideboard is pretty self explanatory, just pick the right colors. Prismatic Ward is best used on the Mounted Archer beacuse he can then block all the creatures he wants and not be damaged. Prismatic Ward is also good on the Wall of Resistance because if someone disenchants it, it will be big enough to block anything. The main idea is to protect your self with your clerics and COPs, attack with your shadows, and kill creatures with your archers.
