This quest mage deck works for both Galakrond final boss matches of the Galakrond's Awakening: Week 4. Using the extra turn from the quest for infinite Fireball. So one deck for the E.V.I.L and League of Explores sides.
There is an "elemental package" in the deck that work together both Glacial Shard, Mana Cyclone and Elemental Allies. It gives you card draw, freeze and spells that didn't start in your deck. If you miss one, replace the others cards.
Win rate %
I played 10 games against Galakrond from the E.V.I.L. and the win rate was 40%. Against the match from the Explorers side, the win rate is around 100%, it is super easy with this deck.
