This is a ridiculous deck when it comes to drawing cards. I think, .if I read it right; if you play Reclaim the fallen that you actually get Josef's attachment search for every dwarf. That would perhaps be unbearable so I went for the Mining Tunnels for restricted. I don't think this thing would be all that competitive in tournament play but if you ever needed practice shuffling...

Develop the battlefield and run em over. "Good, bad...I'm the Serpent Slayer with the Hellblasta!"

Any deck with Serpent Slayers needs Wake the Mountains, especially with Verna running around.

Hmm...yeah I considered wake the mountain but it got axed as I trimmed down to 50 while still maintaining at least 15 attachments as I believe that is the minimum ratio (30%) to get enough "bang for bugmans buck". Perhaps swap it out for the Keystone Forge? That might drop the support card ratio low enough to justify replacing the Dwarf Cannon crew with the Grudgebringers.

Why not Bugman's Rangers as they get the power bonus for having the attachments on them?

I didn't put the Rangers in because I wanted to maximize the card draw ability of Bugman's with cheap units (1s and 2s). Every card you pull out of the deck increases your probability of the hellblaster/serpent slayer winning combo. That said you could probably swap the rangers for the Defenders of the Hold and not see too much difference.

I didn't see it at first but I think Rune of Resistance is better than the Gromril Armour. Keeping your serpentslayas or hellblasting unit alive FTW!

With Mining Tunnels you could get rid of the Oathstones, keep the armour, and add Rune of Resistance.
