Just a bit of a new spin on an old fun deck.
Using Big Bad Voodoo on your giants now has a 50% chance to summon a Grave Horror. This can really mess up how your opponent deals with the board.
Spirit of the Frog is a great way to pull specific cards from your deck when you need them. For instance, using Rain of Toads will automatically draw and upgrade your Lesser Spellstone into a Sapphire Spellstone.
Krag'wa, the Frog can be a bit tricky to play, but is best used with non-overload cards like Hex or Healing Rain. Annoy your enemies with more healing and transforms than they're used to.
I'm still working on the deck and it's tough to test when many players are still using refined decks from before the expansion. Any advice is appreciated.
