Strategy and Deck Building

The Ragnaros the Firelord fight is in fact a two part battle. The first part of the fight is against Majordomo Executus, a relatively straightforward boss with one noteworthy catch. His deck carries a massive 10 Molten Giants, meaning that as soon as you lower his health below 20, he will start to punish you with multiple 8/8 minions each turn.

The second part of the fight is the Ragnaros form itself, which carries an extremely powerful Hero Power, and 16 total life on Normal and 60 on Heroic. The Ragnaros form is very difficult to compete with for long periods of time, and as such, it is best to set up a quick win for when you kill Majordomo, so that you do not have to compete with the Ragnaros form for multiple turns.

The strategy for this boss is fairly consistent between both Normal and Heroic modes, you will want to stall the game out in the Majordomo form, refraining from attacking him below 20 health in order to not activate his Molten Giants. By keeping the boss in his weaker form, you can use the extra time to build up a huge board, which is able to kill Ragnaros in a single turn once he is summoned.
