This is a fun deck I put together that consists of reducing the cost of Lesser Sapphire Spellstone or Ancestor's Call with your Emperor Thaurissan so that we can get Malygos out and copy it with Lesser Sapphire Spellstone. We have Lorekeeper Polkelt to draw everything we need for the combo and then Witchwood Piper to draw our Spirit of the Frog a bit more consistently. It’s worth noting that we only need to reduce the cost of either Ancestor's Call or Lesser Sapphire Spellstone by 1 which is great because we only need to reduce the cost of 1 combo piece. Try to store your spells for a big Spirit of the Frog if you can because this is a cycle deck in theory.
