I wouldn't be surprised if the pirates ran the Crawler, honestly. the new Ooze looks a lot better in my book, otherwise I think decks like Control Warrior (taunt quest thingie) and such will counter pirates enough that there will be less pirates around. remember, even now Control Warrior wrecks pirates however it's unplayable just because of Jade Druid and Kazakus.
so I predict there'll be a struggle between jade druids, pirates and taunt warriors taking turns in popularity, countering eachother.
