Dimir Terror is graveyard-dependent in multiple ways: Thought Scour and Mental Note fuel Tolarian Terror's cost reduction, Gurmag Angler needs delve fodder, and Sneaky Snacker returns itself from the graveyard once they draw a third card in a turn — Faerie Macabre disrupts all three by exiling cards out of their yard. Hydroblast has few red targets here beyond Abandon Attachments, so bring in Dispel instead; lean on two Faerie Macabre for graveyard disruption alongside Dispel to support your maindeck Arcane Denial. Since their clock relies partly on small evasive creatures rather than a full alpha strike, trim one Tangle, two Weather the Storm, and two Stream of Thought (which would only feed their graveyard) for the interaction and graveyard hate.
