This deck uses a truckload of Spell Damage minions to boost your spells and kill your opponent quickly. Violet Spellwing gives it a badly needed Turn 1 play, and Azure Explorer is a hefty improvement over Cosmic Anomaly. The cherry on top is Malygos, Aspect of Magic, an versatile card which can give you an appropriate response for a number of situations. Overall, DoD gave this archetype an insane boost, and it will probably be one of the most deadly aggressive decks in the meta.
Blast Wave is anti-aggro tech which improves substantially when boosted by Spell Damage cards (especially Celestial Emissary). However, if the meta is slow enough, it can be cut for something else. I also like the stickiness of Mana Reservoir, which is why I selected it over Spellshifter. However, you can get away with using either of them.
