Mulligans
General Mulligans
Really you only keep Murloc Tidecaller and Murmy just so you can get to the Prismatic Lens. Keep in mind this deck wins almost 100% of the time when you use Prismatic on 3 or 4, so you really do want to hard mulligan for that card.
Murloc Paladin but with Scalelord and Dragonqueen. I did try the dragon synergy murlocs in this deck initially, but Tasty Fin was good but inconsistent (If you don’t have Finley or Dragonqueen, replace it with Tasty Flyfish) while Skyfin was not good at all.
