I wouldn’t change a card but for the sake keeping conversation rolling here some card you could substitute. I do think Quest rogue is massively underrated .
Captain parrot is an absolute potato of a card but you need the consistency, so I’ve come the conclusion it’s a necessary evil. For that reason to you can’t really run any other pirates, as you need the tutor for bloodsail.
Flex cards in the list would be novice engineer and vicious scalehide
crab rider (early game control)
guardian augmerchant (Helps mid game trades)
Wax elemental (more beefy then target dumb worst tempo)
Questing explorer (in my opinion worst then novice as you loss post quest card draw)
