Mullligan for Zap! and Spirit of the Frog within reason. you will use these on turn 4+ to cycle into all your 2 mana buffs by playing Zap!/Coin with Spirit of the Frog to draw in to your Unstable Evolution and then cycle that on another minion to draw all your 2 mana buffs. Ideally you can combo any of these buffs with Zentimo or Electra Stormsurge. You don't have to set this combo up super early though, this deck has A LOT of board pressence, so you should be able to bide your time until you have a Zap! and a Spirit of the Frog.

Other noteable combos are using Ancestral Spirit or Earthen Might or Unstable Evolution or Hex or Earth Shock with Zentimo, or Electra Stormsurge.

Also remember you dig for specific cards  depending on how you use Spirit of the Frog for example casting a 2 mana spell to guarentee draw your Lightning Storm vs aggro, or Lightning Storm to draw in to your Hex if there's a big threat to deal with or you suspect there will be.

In general this deck has a lot of versatile synergies that allow for huge swing turns while having a strong board presence from the elemental tribe allowing you some time to set up those combos.

Also Also  if you ever just have to run out Spirit of the Frog and don't have a great way of protection it/afraid of dying to aoe next turn, you can always cast Ancestral Spirit and it respawns with stealth so unless they have a silence effect you should be good.
