I made top4 last saturday with Grow-a-goyf here in Quebec. I used Steve's list, but I cut some cards including the drains for 3 Counterbalances and 2 Top's. As a legacy player, i'm kinda sold on those and I found myself mana burnin' way to often for my liking with drain's mana... Top also play quite nice with bob as everybody know: I was able to drop two confidants quite often, without fear of getting killed by them, as we run quite few high cc (FoW, Tendril's, Gush, Inkwell)!
Anyway counterbalances were amazing, they won me some games I had no business to win. I also used some Mongoose sideboard, as a counter-threads strategy: that too worked quite nicely, won me my top8 match on his own against Landstill. I had 2 Trygon side for the aggro shop match, maybe because i'm a BUG fish player;) and I have to say that I won the match on this guy back only!
Cheers! Thank you Steve for that list, I had a load of fun during the weekend!

against oath. Stifle even saved my butt against a Duplicant while playing vs Aggro shop!!! Not to mention that it's good against storm based strategies and that your opponent will be forced to play around it even if you run only two copies!
