In the fourth encounter of the chapter "The Big and the Bad", you're fighting Supremus.
- Don't take your low-Health minions to this fight as you would just gift Abyssals to the boss. You might want to avoid Reborn as well for the same reason.
- Don't go too wide as the boss has the means to punish you for doing so with a variety of AoEs.
- Given the Hero Power and the amount of removal that the boss has, a control deck would be the wisest choice for this fight.
Watch Out For These Cards
Thanks to Supremus' high-Attack minions, Shadowflame is almost certainly going to be a strong spell that can turn the tide of battle if you're not careful.
Mortuary Machines will provide you with some potentially unwanted Reborn-tokens, which the boss can exploit with his Hero Power. Luckily, Supremus seems rather hesitant of playing them.
