Considering Battlepickaxe is practically an infinite weapon in this deck, it might be worth it to put in 1 more Weapons Expert just for the extra attack. Blackrock 'n' Roll and Lor'themar Theron could give you massive buffs for the copy minions but are probably too slow.
The mech package gives you much better early game and also decent taunt synergy (especially Bronze Gatekeeper and Zilliax
Edit: I missed the interaction with Dread Corsair that enables you to attack with the weapon immediately, definitely had to add that for 1 Frequency Oscillator and 1 Annoy-o-Tron
