Jund Artifact Sacrifice relies on cheap artifacts (Experimental Synthesizer, Springleaf Drum, Oni-Cult Anvil) and Deadly Dispute value chains to grind out damage via Shrapnel Blast, so disrupting their hand and board is key. Go Blank discards two cards, hitting their Deadly Dispute or Thoughtseize before it can set up their engine. The second Culling Ritual sweeps their sea of cheap artifacts and creatures (Greedy Freebooter, Voldaren Epicure, Biotech Specialist, Springleaf Drum, Oni-Cult Anvil) with mana value 2 or less while ramping us. Graveyard Trespasser's hate is low-impact here since their plan isn't graveyard-dependent, so we trade it for proactive disruption and a sweeper.
