Faithless Looting discards Fiery Temper into exile for its madness cost, so Faerie Macabre's graveyard exile does nothing to stop that engine and stays in the board. Darkness is excellent since it blanks an entire turn of combat damage from their attacking creatures, letting you stabilize through their damage-race plan. Weather the Storm gains 3 life per spell cast before it this turn (storm), directly countering their incremental ping damage from Kessig Flamebreather and Guttersnipe. We shave the 4 Architects of Will and the single Repository Skaab since neither answers their fast clock, favoring maximum lifegain and damage prevention instead.

Dimir Control's Counterspell and Dispel are the biggest obstacles to resolving our payoffs, so Duress proactively strips a counterspell before we commit to our key turn. Faerie Macabre is a flying threat/blocker against a deck with very few ways to interact with fliers, and discarding it can exile up to two target cards from a graveyard if needed for value. We shave Architects of Will and Repository Skaab since their card selection is too slow when the opponent already has Brainstorm and Lorien Revealed for their own card advantage — we need to be efficient and resolve threats through a small counterspell suite.

Tolarian Terror and Cryptic Serpent both cost {1} less for each instant and sorcery card in the opponent's graveyard, so Faerie Macabre is premium here — discarding it to exile up to two graveyard cards directly taxes their key threats back up in cost, or it can be cast as a flying blocker if needed. Darkness provides an instant-speed way to prevent all combat damage, buying crucial time against their massive Tolarian Terrors and Cryptic Serpents while holding up mana. We cut Architects of Will and Repository Skaab since their card selection is too slow against a deck with Counterspell and Dispel backup, and we need to be proactive rather than grindy.
