Malygos Druid is a pretty old archetype that utilizes the power of magic to boom on your opponent with cheap spells like Moonfire. This is a combo deck, you are looking to stay alive in the short term and hold off your enemy while you build up your combo pieces to finish them off in one or two turns.
The Boomsday Project buffed this deck in a big way. It got Biology Project as a way to further increase your ability to get closer to having enough mana to finish your combo. You’ve also got Flobbidinous Floop which can give you a second turn Malygos for just 4-mana, which gives you more mana to cast higher cost damage spells.
