Breaking away from this, lets break down the deck and look at the main engine cards:
Marauding Looter - card selection on a moderately good body
Chart a Course - w/ raid, this is a 2 mana divination, which is EXTREMELY strong.
All the other cards seem a little lackluster, so here is my take, it should still be fairly budget.
Above is the link. it costs only 20$, which I think is pretty good. the idea is to outtempo your opponent and jam with mostly evasive pirates. going in heavier on pirate subthemes allow for more payoffs such as Lookout's Dispersal, Dreamcaller Siren, and Fell Flagship. Hope this helps, my analysis isn't great atm because im rushed for time on something else. GL at fnm!
