Hearthpwn

This mech deck aims to use spare part synergy with the ever powerful Archmage Antonidas and the less seen Gazlowe. Using Echo of Medivh on either or both of these legendaries with some spare parts in hand really works out, but even without this there is an aggressive minion curve. Direct damage is limited unless you manage to get some Fireballs from Archmage Antonidas, so you could consider adding Ice Lance in place of Micro Machine for more 1-mana spell synergy with your core legendaries, and damage synergy with Frostbolt.
