Prince Arthas

Encounter Overview

Prince Arthas uses a deck themed around Undead minions, Frost, and Death Knight cards, notably using spells like Obliterate and Pure Cold. Additionally, the boss also has a 0-Mana Hero Power, Scourge Army.

In this encounter you will be given another Pure Libram Paladin deck comprised entirely of Paladin cards. The deck notably includes Pure Paladin cards, Silver Hand Zealot and Silver Hand Crusader, mixed with a wide range of Librams, including special Librams like Libram of Compassion and Libram of Holiness. Additionally, you will have acess to the Divine Storm Rank 2 Hero Power for the duaration of the fight.

The aim of the fight itself is not to kill the boss but instead to simply survive for 13 turns without being overwhelmed by the boss.


Mulligan Strategies

In your opening hand you look for cards that will help slow down the influx of 2/2 Ghouls. Notable Lordaeron Attendant paired with Unbroken Faith or Libram of Wisdom, and Consecration are great for this.


Gameplay Strategies

As the aim of the fight is simply to survive, you should try to set up a position to mitigate as much damage as possible. High-Health Taunt minions like Paragon of Light and Radiant Lightspawn are particularly effective at this due to how they match up against opposing 2/2 Ghouls. if you are able to get this set up, you should try to protect it as much as possible by making use of your Healing effects from Royal Urn, Libram of Compassion, and Libram of Holiness.

If at any point you become overwhelmed on the board, either because of poor draws or because your Taunt minion has died, you can make use of Consecration to clear most of the board to begin trying to build a Taunt minion again.

As the fight continues, take note of how many turns remain as you can make more liberal use of your cards once only a few turns remain to help ensure victory.
