Theyre just Werewolves
First we're adding the remaining good Pirates into the deck: Malcolm, Alluring Scoundrel is particularly great here due to filling our graveyard with reanimate targets, Breeches, Eager Pillager is a super efficient bundle of evasion / card advantage / treasure, Forerunner of the Coalition is terrific tutoring, Kitesail Larcenist temporarily shuts off a wide array of things like opposing commanders, Crafty Cutpurse makes token decks (even treasures) cry, and Lightning-Rig Crew is low-key busted with Malcolm, Keen-Eyed Navigator or Francisco, Fowl Marauder since they don't specify combat damage
Farseek Farseek is great for mana fixing
For example, card draw (Cunning Rhetoric, Enchantress's Presence) removal (Grasp of Fate, Cast Out) and bodies (Sigil of the Empty Throne, Sandwurm Convergence)
