Swords to Plowshares is a spell that most pirate-themed decks wont have access to without a card like Dire Fleet Daredevil
In a deck, you can shoot something while pinging yourself
There are multiple cards that let you either gain lore, exert opponents, gain strength, or draw cards but only when an opponent has a damaged character
non creatures i would run: Lifecrafter's Bestiary, Skullclamp, Return of the Wildspeaker, Inspiring Call, Harmonize, Rishkar's Expertise maybe a few things like Fade from History, Beast Within, Nature's Claim, Collector Ouphe is also really strong since you will be running creatures Sure, the mana doubling can be fun, but is it really needed
