Da Ba Dee Da Ba DIE

This is my first attempt at a Blue Sun deck. Haven't gotten the chance to try it out yet. Besides the general Blue Sun kill-ness, I tried to go with the Superior Cyberwalls thing and get a good bit of barriers. I didn't use exclusively barriers, because that's dumb, but hopefully a well timed Archer can stop the runner's ability to get in long enough for me to score some stuff.

I should probably take out a Cyberwalls and put in another piece of ice, huh? Also, should I be using Shadow? Does that ever reliably tag?
