the AI can't see reflective shield lol...he never make something for sow+ reflective shield
I don't know much about the coding for the AI, but when I was battling one such mono
deck in gold last week I played the reflective shield on the second turn, before the opponent used SoW. once he had a few phase dragons out, i was taking lots of damage, and they didn't play SoW. On the last turn before I was going to lose i played a bonewall to block the dragons, and sure enough, the next turn the CPU immediately played
THREE SoWs and went right through the bone shield.
The only explanation I can see is that he was programmed to not play SoW when reflective is in play.
