Use Grievous Insult to take out opposing submerged/burrowed minions threatening your Orm Infestor or frogs. Be wary of Lacuna Entity snagging your Orm Infestor and pulling into the void. Always drop Devil's Egg while in the subsurface to avoid Just a Rock. Mulligan for defensive sites or Croaking Swamp. Try to start the game with frog generating cards to help with Symmetric Suffering, Swap, Gilman House etc. Always keep Mismanaged Mortuary. Two Mortuaries cancel each other out so if your opponent plays one against you, you can counter it with your own. You can also play cards from your opponent's cemetery in some situations even if they aren't a water deck thanks to the trie sites and Colour out of Space.
