Mountian Giant? For Handlock.

How badly do you need mountain giants for handlock? I have most of the other epics and rares that are required for handlock. I have always wanted to try Handlock. I often play a custom rage warrior variant, as well as some of the basic aggro decks[Zoolock,Hunter,Deathrattle Priest,Ebola Druid]. I dont know what deck I should craft for a control deck? If anyone could give me some advice how to best use my hard earned 635 dust, I’d be much abliged.

Mountian Giant is the keycard in the Handlock deck, beside Molten Giant u have no more important card in it.

I have crafted the both of mountian gaints. I already had opened two molten giants so I am working on crafting the other required cards for a handlock deck.
