- Decks contain three of each special Boom Bot. Two copies are naturally in the deck, and a third copy is generated and drawn on turns 3, 4, and 5.
This brawl is fairly random, so there's not much strategy. Warrior may be a preferable class, since they have lots of good Mech cards to synergize with the Boom Bots. Classes with pinging hero powers can also be helpful for dealing with the Boom Bot that begins in play at the start of the game.
