Hi there! Sorry, I haven't been too diligent in monitoring my own forum.
I still play Vintage but not as much as I used to. Portland, OR, where I am doesn't have many events but I've played some unsanctioned Vintage in Seattle. I even got to lose to Randy Beuhler in one match---but at least I took him to three games.
I usually play Control Slaver but I'd switched over to Grow-A-Tog before they restricted Brainstorm and Gush and most other cheap card drawing. I agree, I don't see that Brainstorm needed to be restricted. I certainly don't think that card is unbalanced in Vintage.
