So every single deck can't win through a Ghost Quarter?

Bucky and my matches:

Gauntlet, Tom and Fable all can't win thought their land getting Ghost Quartered, so that's WW.

For our match it's DD, as we can Ghost Quarter each other's lands. Bucky can activate Geier Reach on the play before my third land, but I can play my Ghost Quarter before that and destroy his factory, even in response to Geier Reach activation if he plays it as his third land. If he trades Ghost Quarter for Ghost Quarter then he doesn't have mana to activate Geier Reach, and I can animate the Colonade before I take lethal.
