this looks pretty good for a budget deck. The only issue I see, is that you are lacking a card advantage engine that can just win you the late game. The best and cheapest option I can think of is
search for azcanta. If you could get anything for the deck, I would recommend getting a 2. More
supreme verdict and
path to exile would be really good to.
Oust is really well positioned right now, and it might be correct to play a 2-2 split between path and
oust.
Oust is also much cheaper than path.
Good Luck
