@eika Although Whrenchmast is ideal because it adds armor to both bombots and does not fully mana block the flame cannon, it is really just a luxury. You could just as effectively play with Golden Cog, which would actually be more efficient in quickly pumping one of the bombots up before exploding, but mana blocks flame cannon, OR use almost ANY Hero Weapon for variety. The hero is essentially a skull sponge in this deck.
