After playing a bit with invasion decks using Harrow to bring forth different types of lands and bringing in all sorts of gold cards, I began to see a problem: I was depleting my hand of cards fairly quickly. Because Coastal Piracy is one of my favorite blue cards, I began toying with the idea of building a deck using CP and Invasion Gold cards, with some counter magic for modest control and protection with Diplomatic Immunity. Just a thought . . . no deck list yet, but I'm working on it.
