What’s the point of swordfish?
A 2/3 for 3 is terrible for just the dredge.
Same for the vessel, I simply don’t see its point in the deck.
Guild trader is needed to reach respectable from hand damage and Scabbs is needed to deal with wide taunt boards like from paladin. Tradeable is also good with gnolls.
Speaking of paladin, Viper is probably a good card since in addition it is a tradable card so it can help with advancing Gnolls early on.
So, for starters I’d remove swordfish and vessel and put in Scabbs, viper, and trader.
