Cheap Hagatha the Vengeful Priest Deck (Heroic Mode) for Galakrond's Awakening

With this Inner Fire deck for Hagatha the Vengeful, you should try to secure the board early with Northshire Cleric or Radiant Elemental to help keep the board clear of minions.

While controlling the board, you should try to draw through your deck as much as possible to find your copies of Divine Spirit and Inner Fire. During this time, you can commit further minions to the board, like Injured Blademaster, as the only AoE available for the boss is Lightning Storm. However, you should not commit to using your Divine Spirits too early as you will make yourself vulnerable to Devolve.

Over the course of the game, you should be able to chip away at the boss's Health, eventually setting them up to burst damage from Divine Spirit and Inner Fire combos. Alternatively, if you find yourself low on cards, you can commit to comboing a minion earlier and winning over two turns. However, you should wait until you have seen at least one copy of Devolve played before trying this.
