I am starting to convert as well. I played a mono-white stacks deck yesterday as wel, and I took the match 2-1. Duress/Thoughtseize is 100x better with this matchup than is chant. I was able to duress him turn one in both games I won, and that can be devastating to them.

So my question is, how do you get past Merfolk or some other deck that runs at least 8 counterspells? Is that where Bob saves the day?
