You could add thragtusk, after a game reset the 3/3 beast comes to finish your opponents

You could splash black for Wall of Blood

and Oracle of Nectars and Engulfing Slagwurm

Add Well of Lost Dreams and Loxodon War Hammer instead of Unnatural Predation and 4 Forests

Add primeval bounty

Agent of the fates, Herald of Torment, King Macar, the Gold-Cursed, Underword Connections Dark Prophecy, Sanguine Bond, Whip of Erebos for more Black Devotion and a like for being creative

Hopefully all within the budget of your budget deck.

It does make it not Modern tho

Maybe, Doubling Season, Gleancrawler, Privileged Position

I like Silent Arbiter with this deck

Panoptic Mirror

you could put Pariah in there to have some more fun

Maybe Torper Orb in SB for Splinter Twin

Awesome, but you need another blightning, they are insane

Sorry man, thought they were cheap enough

I would add Bile Blight instead of lobber crew, it can't do much. Also Drown in Sorrow is a must for SB against aggro
Thoughtseize and Hero's Downfall are good also, but may be to expansive for your semi-budget deck

I would add Bile Blight instead of lobber crew, it can't do much. Also Drown in Sorrow is a must for SB against aggro.

Maybe Goblin War Chief, Goblin Recruiter or Goblin Matron?

Nice, I like quest for the goblin lord

Maybe Explore?
