Tolarian Terror gets cheaper for every instant and sorcery in the opponent's graveyard, and Gurmag Angler uses delve to exile graveyard cards to reduce its cost, so Faerie Macabre is excellent here — discarding it exiles up to two of their graveyard cards, directly taxing both key threats. It also blocks Sneaky Snacker, which otherwise returns itself from the graveyard when they draw a third card in a turn. Duress strips their Counterspell or Snuff Out before we commit to a key turn. We trim Repository Skaab and Architects of Will since card selection is too slow against a deck with proactive interaction and its own card draw engine.
