The Excavate cards are an obvious choice; you want to be able to play them on curve or ideally as fast as possible. Schooling is amazing to play turn 1 and gives you resources to help clean up a board or they become 4 drops if they’re still in hand before playing Azerite Murloc. Scalding Geyser is amazing because it can Dredge, which is extremely useful in a deck that needs specific cards to achieve its goal. You’ll be using it a lot to take out low health minions or play it turn 1 to hopefully force a draw into an Excavate card. Lastly, the two Murlocs, Cactus Cutter and Clownfish, are good keeps because you want something to play early and both provide value in their own way. Cutter will draw a spell, which we run 2 that Excavate, and he can be a nice Taunt if the spells played in the same turn. Clownfish is nice because he helps you mana cheat your next 2 Murlocs; this is incredibly useful since every Murloc in the deck does something immediately when played.
This deck uses a Murloc package to draw Spells, draw 3 Murlocs from Gorloc Ravager, and reduce the cost of Murlocs, including our final reward.
