Lightning Bloom ramps Snowfury Giant by 4 mana, which is pretty sweet. I also like the synergy between Lesser Sapphire Spellstone and Vessina, or Spellstone + Squallhunter and a burn spell. I added in both Overload unlocking cards, Lava Shock and Eternal Sentinel, to offset the huge Overload created by things like Elemental Destruction and the various 2 mana Overload cards. I get the feeling there will be more cards to support this archetype in Scholomance Academy, but I wanted to get started on a theorycraft, so I figured I'd share it!

Also, Lightning Bloom doesn't seem to be showing up in the decklist, but it's a 2-of and core to the deck. Must be a bug with the deckbuilder.
