There are a few cards that help fill your graveyard (besides Admiral Brass herself), but not so many that you can expect to constantly be recurring Pirates from your graveyard
UN-FAIREST OF THEM ALL Since non-green builds of Enchantress lose access to its defining draw engines and mana ramp, chain-casting cheap enchantments is not going to be as efficient
At the beginning of your end step, create a 5/5 black Demon creature token with flying, then mill two cards
Getting to your big plays a turn early is excellent, and coming down on turn one is even more so
Impulse draws and other cast-from-exile strategies gain support each set, so this looks like a potent stax piece that shuts down entire decks
Unless your team is hyper-aggressive, that extra card from being draw is a huge late-game advantage
