Burgrak Cruelchain Boss Guide for Trial by Felfire

Burgrak Cruelchain is a unique encounter in that the boss itself is not killable. Instead, the aim of the encounter is for you to play a total of 12 Spare Parts throughout the fight. The boss aditionall starts with 2 Bonechewer Brawlers and a Dormant Broken Demolisher on the board, putting you at a massive early disadvantage.

The boss uses a Mech deck themed around generating Spare Parts. The Mechs played by the boss help activate the Grease Monkey Hero Power to provide Spare Parts for both players.

You will be provided with a Miracle-style deck consisting of cards that benefit playing from playing lots of cards, such as Edwin VanCleef, Questing Adventurer, Mana Addict, and Arcane Anomaly. Additionally you will have the 4 Outcasts you have recruited so far, Karnuk, Outcast, Sklibb, Outcast, Shalja, Outcast, and Baduu, Outcast added to your deck after your Mulligan.

In your opening hand, you should look for a mix of good early-game plays like Spymistress to help deal with the initial Bonechewer Brawlers, and cards that can snowball heavily like Questing Adventurer or Edwin VanCleef to take advantage of the Spare Parts you will be getting.

In the early game, your only focus should be gaining control of the board, making use of Spymistress, SI:7 Agent, and any other early game minions you have to contest the board. Once you are able to start contesting the board, your aim should be to use any Spare Parts you have to try to build a big minion like Questing Adventurer or Edwin VanCleef on the board. Once you have a big minion in play, you can use it to make multiple favourable trades, allowing you to take full control of the board with any minion you have. From this position, you should simply continue to control the board as you wait for the boss to play enough Mechs for you to generate the 12 Spare Parts required to complete the encounter.
