To Destroy or Not

Mostly this deck annoys the opponent early on; the goal is choosing one location to win outright and protecting it with armor in case you can't get Cosmo out to suppress the Destroyer's reveal effect. Colossus is a nice safeguard outside the armor, and Crystal is sticking around because 4 points of power isn't bad, but also she can help you redraw if you don't have the destroyer in your hand yet.
