No, you're right. I thought there was a difference in the 2 approaches...but there really isn't, not funcionally. The Grapeshot win needs Glimpse a lot more though...I've read several posts here where folks have powered out a Regal Force via Living Wish with a mana-lord and drawn into Emrakul without Glimpse. I think (with my little brain) that the Emmy/wish builds don't need to rely on Glimpse as much as the storm setup does.

Then again, I AM retarded...lol.
