This is a true budget deck using the cards from my own incomplete collection. It contains no legendaries or campaign cards.
This deck is an aggressive midrange style and was built to combat an aggro-heavy meta. If your meta is dominated by control you might want switch to an aggro list, something like Rakano or Stonescar Zoo. (Yes, I said Stonescar Zoo, not
Stonescar Burn. You can check out my zoo list here: Stonescar Zoo (true budget, no legendaries)
(edit) Slightly updated list fares better against non-aggro. I think :)
