Bomb Warrior is a new Warrior archetype from Rise of Shadows. While we had some cards that shuffle “Bombs” into the opponent’s deck before (even as far as GvG, where Iron Juggernaut shuffled a 10 damage mine), Rise of Shadows pushed this synergy. Expansion has added two more Bomb cards – Clockwork Goblin and Wrenchcalibur, as well as a Bomb synergy in a form on a third Dr. Boom – Blastmaster Boom.
New Warrior Legendary is incredibly powerful. If you were playing back when Dr. Boom was common, you will understand why – especially since the new one will often summon 6 Boom Bots instead of 2. While it’s still early, Bomb Warrior looks quite promising.
